Creating High-Performance Real-Time Charts with JavaScript

The world of data visualization has undergone significant transformation over the past few years, with advancements in technology making it possible to create highly interactive and dynamic charts and graphs. One of the critical components in this evolution is the use of high-performance JavaScript chart libraries. Today, we learn more about the creation of real-time charts using such libraries, a topic on which I’ve collaborated closely with a developer to bring you the most accurate and practical insights.

The Importance of Real-Time Data Visualization

Real-time data visualization is crucial across various sectors, from finance and trading to medical research and aerospace. The ability to visualize data as it is generated allows for quicker decision-making and more responsive operations. Whether tracking stock prices, monitoring patient vitals, or observing real-time telemetry data from vehicles, the need for real-time updates in charts is universal.

The Technical Backbone: WebGL and WebAssembly

The backbone of high-performance JavaScript charts lies in technologies like WebGL and WebAssembly. WebGL, or Web Graphics Library, allows JavaScript to execute GPU-accelerated graphics, making it possible to render complex and data-intensive charts directly in the browser. This is especially beneficial for real-time applications as it ensures smooth and fast rendering even when dealing with large datasets.

WebAssembly, on the other hand, allows code written in multiple languages to run at near-native speed in web browsers. By leveraging WebAssembly, JavaScript chart libraries can perform complex calculations and data manipulations quickly, further enhancing performance.

Leveraging Hardware Acceleration

One of the standout features of advanced JavaScript chart libraries is their ability to leverage hardware acceleration. By utilizing the GPU for rendering, these libraries can handle millions of data points and multiple chart series without compromising on performance. This is particularly important for applications requiring real-time updates, as it ensures that the user interface remains responsive and smooth.

Creating Complex Interactions

Interactivity is a key component of modern data visualization. Users need to interact with charts to derive insights, such as hovering over data points to see detailed information, selecting and zooming into specific areas, or dynamically updating the data being visualized. Advanced chart libraries provide robust APIs that allow developers to create these complex interactions effortlessly. For instance, callbacks on series hover, selection, and data-point interactions enable a high degree of user engagement and functionality.

Building Interactive Dashboards

Dashboards that display multiple linked charts are common in industries like finance, medical research, and operations management. These dashboards allow users to see various data points and trends simultaneously and understand their correlations. JavaScript chart libraries facilitate the creation of such dashboards by providing features like linked zooming and panning, synchronized cursors, and dynamic addition or removal of chart panes.

Creating these interactive dashboards involves grouping multiple charts and synchronizing their interactions. This means that actions performed on one chart, such as zooming or panning, are reflected across all linked charts. This level of interaction enhances the usability and effectiveness of the dashboards, allowing users to gain insights quickly and efficiently.

The Role of Annotations and Markers

Annotations and markers play a crucial role in enhancing the readability and functionality of charts. By adding annotations, developers can highlight important data points, trends, or events, making it easier for users to understand the data. JavaScript chart libraries offer powerful annotation APIs that allow for the placement of various markers and shapes at specific data points or relative coordinates.

These annotations can be interactive, allowing users to click, drag, and resize them. This interactivity is useful in applications where users need to mark and comment on specific data points, such as in collaborative environments or analytical tools.

Enhancing User Experience with Cursors, Tooltips, and Legends

To further improve the user experience, advanced JavaScript chart libraries provide features like cursors, tooltips, and legends. Cursors, such as crosshairs and draggable vertical lines, help users track data points accurately. Tooltips provide additional information when users hover over data points, which is essential for detailed data analysis.

Legends are another critical feature, offering a quick reference to the data series displayed in the chart. By interacting with the legend, users can show or hide specific series, enhancing the focus on particular data points or trends.

Zooming and Panning Capabilities

Zooming and panning are fundamental interactions in data visualization, allowing users to focus on specific data ranges or explore different parts of the dataset. Advanced chart libraries offer sophisticated zooming and panning capabilities, which can be controlled programmatically or via user interactions.

These libraries provide APIs to zoom and pan in various directions and to scale the chart dynamically. This functionality is particularly useful in real-time applications where new data is continuously added, and users need to navigate through the evolving dataset.

Customization and Theming

Customization is key to integrating charts seamlessly into any application. JavaScript chart libraries come with various theming options, allowing developers to match the charts’ look and feel with the application’s overall design. Custom themes can be created to define colors, fonts, and other stylistic elements, ensuring that the charts are visually cohesive with the rest of the application.

Moreover, these libraries often provide animation options to enhance the visual appeal of charts. Animations can be applied to data transitions, user interactions, and style changes, making the charts more engaging and informative.

Financial and Stock Charting

In the financial sector, the ability to visualize stock data accurately and in real-time is crucial. Advanced JavaScript chart libraries support various financial chart types, such as candlestick, OHLC (Open, High, Low, Close), and mountain charts. These charts are essential for traders and analysts who need to monitor market trends and make informed decisions quickly.

Financial charts often require multiple panes to display different data series, such as price, volume, and indicators. By linking these panes and synchronizing their interactions, JavaScript chart libraries provide a comprehensive and intuitive way to visualize complex financial data.

Real-Time 3D Charts

For applications requiring three-dimensional data visualization, JavaScript chart libraries offer WebGL-powered 3D charts. These charts allow for dynamic updates and seamless interactions, such as zooming, panning, and rotating the 3D scene. Real-time 3D charts are particularly useful in fields like medical imaging, scientific research, and engineering, where understanding the spatial relationships between data points is crucial.

Conclusion

Creating high-performance real-time charts with JavaScript requires a deep understanding of the underlying technologies and the specific needs of the application. By leveraging WebGL and WebAssembly, utilizing hardware acceleration, and providing robust interactivity and customization options, modern JavaScript chart libraries enable developers to create powerful and responsive data visualizations.

Through this exploration, we have highlighted the essential features and capabilities that make these libraries indispensable tools for real-time data visualization. From interactive dashboards to financial charting and 3D visualizations, the possibilities are vast and continually expanding, driven by the ongoing advancements in web technologies.

HTML Graphics

HTML provides various ways to include and work with graphics directly on web pages. The most common methods include using Canvas, SVG, and other techniques like CSS and WebGL for advanced graphics.

1. Canvas (<canvas>)

Purpose: The <canvas> element is a container for graphics that can be drawn using JavaScript. It's ideal for drawing shapes, making animations, creating charts, and developing games.

How It Works: The <canvas> element itself is just a container; the drawing is done with JavaScript, using a 2D or 3D context.

Attributes: width, height

Example: Drawing a rectangle on the canvas.<canvas id="myCanvas" width="200" height="100"></canvas><script> var canvas = document.getElementById('myCanvas'); var ctx = canvas.getContext('2d'); ctx.fillStyle = "blue"; ctx.fillRect(10, 10, 150, 80); </script>

Use Cases:

Creating dynamic graphics and animations

Developing browser-based games

Rendering charts and graphs

2. SVG (Scalable Vector Graphics) (<svg>)

Purpose: The <svg> element is used to define vector-based graphics that can be scaled without losing quality. SVG is XML-based, which means each element is accessible and can be manipulated via CSS and JavaScript.

How It Works: SVG graphics are defined in XML format, which makes them easy to edit and manipulate.

Example: Creating a simple circle with SVG.<svg width="100" height="100"> <circle cx="50" cy="50" r="40" stroke="black" stroke-width="3" fill="red" /> </svg>

Use Cases:

Icons and logos that need to be scalable

Creating complex vector illustrations

Responsive designs where graphics need to scale

3. CSS for Graphics

Purpose: CSS can be used to create and manipulate graphics through styles like gradients, shadows, and transformations.

How It Works: By using properties like background-image, border-radius, box-shadow, and transform, you can create graphic effects directly in CSS without using images.

Example: Creating a gradient background with CSS.<div style="width: 200px; height: 100px; background: linear-gradient(to right, red, yellow);"> </div>

Use Cases:

Adding simple graphical effects like gradients or shadows

Creating animations using keyframes

Designing layouts with complex shapes

4. WebGL

Purpose: WebGL (Web Graphics Library) is a JavaScript API for rendering 3D graphics within a web browser without the use of plugins.

How It Works: WebGL is based on OpenGL ES and provides a way to create complex 3D graphics and animations directly in the browser.

Example: WebGL is more complex and typically requires a JavaScript library like Three.js to simplify development.<!-- This is a simplified example, WebGL requires more setup --> <canvas id="glCanvas" width="640" height="480"></canvas> <script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/r128/three.min.js"></script> <script> var scene = new THREE.Scene(); var camera = new THREE.PerspectiveCamera(75, window.innerWidth/window.innerHeight, 0.1, 1000); var renderer = new THREE.WebGLRenderer({ canvas: document.getElementById('glCanvas') }); renderer.setSize(window.innerWidth, window.innerHeight); document.body.appendChild(renderer.domElement); var geometry = new THREE.BoxGeometry(); var material = new THREE.MeshBasicMaterial({ color: 0x00ff00 }); var cube = new THREE.Mesh(geometry, material); scene.add(cube); camera.position.z = 5; var animate = function () { requestAnimationFrame(animate); cube.rotation.x += 0.01; cube.rotation.y += 0.01; renderer.render(scene, camera); }; animate(); </script>

Use Cases:

Creating complex 3D visualizations

Developing 3D games and simulations

Creating immersive virtual reality experiences

5. Inline SVG vs. <img> with SVG

Inline SVG: Directly embeds SVG code into the HTML, allowing for CSS and JavaScript manipulation.

<svg width="100" height="100"> <rect width="100" height="100" style="fill:blue" /> </svg>

<img> with SVG: Embeds an SVG file as an image, which is more static and less interactive.

<img src="image.svg" alt="Description">

Choosing the Right Method

Use <canvas> for dynamic, scriptable graphics.

Use <svg> for scalable, static graphics or when you need fine control over vector elements.

Use WebGL for 3D graphics and complex rendering tasks.

Use CSS for simple shapes, gradients, and animations.

These HTML5 graphics tools enable a wide range of visual possibilities, from simple shapes and icons to complex animations and 3D environments.

Every market is ruled by certain common concepts, and JavaScript development is no exception. The product lifecycle is a concept that you can apply to several different environments to understand and predict their behavior. It is a business concept that helps us understand the stages that a product goes through during its life, explaining the impact of these stages on its popularity measure—in most cases, sales. If we observe market behavior patterns, we can estimate the current stage of a product and therefore make some predictions about its popularity. There are four stages: introduction, growth, maturity, and decline, and on the chart above, you can see the impact on expected product sales for each stage. For example, smartphones sales aren’t growing like five years ago—actually, quite the opposite is true—so we can fairly say that smartphones are getting into their maturity stage. In the past few years, we’ve seen the introduction of a lot of new technologies in JavaScript, but we needed time to see how the market was going to adopt them. Nobody wants to be the specialist on another promising technology that ends with zero adoption. Now, however, is the time to take another look. In this article, I will take a look at how popular JavaScript is becoming and the factors that may have affected this popularity, and I will try to predict what the future of JavaScript will look like. The Future of JavaScript Language Features Since the European Computer Manufacturers Association (ECMA) established the year-based release cycle for ECMAScript, a standardized JavaScript specification, we haven’t seen a lot of new features coming to the language—just a few each year. This could be one of the reasons we saw an increase of adoption of languages that compile to ES5 like TypeScript or ReasonML, both bringing features to the language that are highly requested by the community. This is not new—JavaScript went through this process before (CoffeeScript) and, in the end, those features ended up being merged into the language standard itself, and that’s probably the future that we can expect for these new typed features, too. But now we are starting to see a game changer move in the compile-to-js market with the increasing availability of WebAssembly in the browsers. Now, we can use almost any language and compile it to run at almost native speed in a browser and, more importantly, we are starting to see support for future-proof features like support for threads that will allow us to take advantage of the multi-processor architecture that represents the inevitable future of all devices. The official toolchain for WebAssembly will help you to compile C/C++, but there are a lot of community provided compilers for different languages, like Rust, Python, Java, and Blazor (C#). Particularly, the Rust community is pretty active and we started to see complete front-end frameworks like Yew and Dodrio. This brings a lot of new possibilities to browser-based apps, and you only need to test some of the great apps built with WebAssembly to see that near-native browser-based apps are a reality now, e.g., Sketchup or Magnum. Adoption of typed languages that compile to ES5 is mature enough, the players are well established, and they won’t disappear (or be merged with ES) in the near future, but we’ll see a slow shift in favor of typed languages with WebAssembly. Web Front-end Frameworks Every year, we see a big fight on the front-end frameworks market for the web, and React has been the indisputable winner for the past few years—since the introduction of their game-changer technology, the Virtual DOM, we saw an almost obligated adoption from their counterparts in order to remain relevant in the battle. Some years ago, we saw the introduction of a radical new approach to web application development with Svelte, the “compiler framework” that disappears at compile time leaving small and highly efficient JavaScript code. However, that feature was not enough to convince the community to move to Svelte, but with the recent launch of Svelte 3.0, they introduced real reactive programming into the framework and the community is thrilled, so perhaps we are witnessing the next big thing in front-end frameworks. Inspired by the destiny operator: var a = 10; var b <= a + 1; a = 20; Assert.AreEqual(21, b); Svelte brings reactivity to JavaScript by overloading the use of label statements with reactivity at compile time by instructing the code to be executed in topological order: var a = 10; $: b = a + 1; a = 20; Assert.AreEqual(21, b); This is a radical new idea that might help in different contexts, so the creator of Svelte is also working on svelte-gl, a compiler framework that will generate low-level WebGL instructions directly from a 3D scene graph declared in HTMLx. Needless to say that React, Angular, and Vue.js won’t disappear overnight, their communities are huge, and they’ll remain relevant for several years to come—we are not even sure if Svelte will be the actual successor, but we can be sure of something: We’ll be using something different sooner or later. WebXR and the Future of the Immersive Web Virtual reality has been struggling for the past 60 years to find a place in the mainstream, but the technology was just not ready yet. Less than ten years ago, when Jon Carmack joined Oculus VR (now part of Facebook Technologies, LLC), a new wave of VR started to rise, and since then, we’ve seen a lot of new devices supporting different types of VR and of course the proliferation of VR-capable applications. Browser vendors didn’t wanted to lose this opportunity, so they joined with the WebVR specification allowing the creation of virtual worlds in JavaScript with WebGL and well-established libraries like three.js. However, the market share of users with 6dof devices was still insignificant for massive web deployments, but the mobile web was still able to provide a 3D experience with the device orientation API, so we saw a bunch of experiments and a lot of 360 videos for a while. In 2017, with the introduction of ARKit and ARCore, new capabilities were brought to mobile devices and all sorts of applications with AR and MR experiences. However it still feels a little unnatural to download one specific app for one specific AR experience when you are exploring your world around you. If we could only have one app to explore different experiences… This sounds familiar. We solved that problem in the past with the browser, so why not give it another shot? Last year, Mozilla introduced the WebXR Device API Spec (whose last working draft, at the time of this writing, is from two weeks ago) to bring AR, VR, and MR (ergo XR) capabilities to the browser. A few of the most important browser vendors followed with their implementation, with an important exception: Safari mobile, so to prove their point, Mozilla released a WebXR capable browser under the iOS platform WebXR Viewer. Now, this is an important step because the combination of AR and VR brings 6dof to mobile devices and mobile device-based headsets like Google Cardboard or the Samsung Gear VR, as you can see in this example, increasing the market share of 6dof devices by a large margin and enabling the possibility of a large-scale web deployment. At the same time, the guys at Mozilla have been working on a new web framework to facilitate the creation of 3D worlds and applications called A-Frame, a component-based declarative framework with HTML syntax based on three.js and WebGL, having just one thing in mind—to bring back the fun and ease of use to web programming. This is part of their crusade to the immersive web, a new set of ideas on how the web should look like in the future. Luckily for us, they are not alone, and we’ll start to see more and more immersive experiences on the web. If you want to give it a try, go ahead download the WebXR Viewer and visit this site to see the possibilities of the immersive web. Once again, standard browser-based apps won’t fade in a year or two—we’ll probably always have them. But 3D apps and XR experiences are growing and the market is ready and eager to have them. Native Support for ES6 Almost every technology invented in JavaScript in the past decade was created to solve problems generated by the underlying implementation of the browsers, but the platform itself has matured a lot over these past few years, and most of those problems have disappeared, as we can see with Lodash, which once reigned the performance benchmarks. The same is happening with the DOM, whose problems once were the actual inspiration for the creation of web application frameworks. Now, it is a mature API that you can use without frameworks to create apps—actually, that’s what web components are. They are the “framework” of the platform to create component-based apps. Another interesting part of the platform evolution is the language itself. We’ve been using Babel.js for the past few years to be able to use the latest features of ECMAScript, but since the standard itself started to stagnate a little bit in the last few years, that was enough time to allow the browser vendors to implement most of their features, including native support of the static import statement. So now, we can start to consider the creation of applications without Babel.js or other compilers since we have (again) the support of the language features in the platform it self, and since Node.js uses the same V8 VM as Google Chrome, we’ve started to see stronger support of ES6 in Node.js, even with the static import statement under the experimental-modules flag. This doesn’t mean that we’ll stop seeing apps being compiled at a professional level, but it means that starting with a browser-based application will be easy and fun as it once was. Server-side JavaScript Even though JavaScript started with server side in 1995 with the Netscape Enterprise Server, it wasn’t until Ryan’s Dahl presentation in 2009 that JavaScript started to be seriously considered for server-side apps. A lot of things happened in the past decade to Node.js. It evolved and matured a lot, creating once again the opportunity for disruption and new technologies. In this case, it comes from the hand of its very own creator, Ryan Dahl, who has been working on a new perspective of server-side secured apps with Deno, a platform that supports natively the latest language features as async/await, and also the most popular compile-to-js language TypeScript, targeting the best performance thanks to their implementation in Rust and the usage of Tokio, but more importantly with a new security philosophy that differentiates it from most of the server-side platforms like Python, Ruby, or Java). Inspired by the browser security model, Deno will let you use the resources of the host only after the user explicitly granted the permissions to the process, which might sound a bit tedious at the beginning, but it might result in a lot of implications by allowing us to run unsecured code in a secured environment by just trusting the platform. Node.js will still be there in the future but may be we’ll start to see serverless services like AWS Lambda and Azure Functions to provide the Deno functionality as an alternative to provide unsecured server-side code execution on their systems. Conclusion These are exciting times in the JavaScript world—a lot of technologies have matured enough to leave space for innovation, the active community never stopped to amaze us with their brilliant and incredible ideas, and we expect a lot of new alternatives to well-established tools since their mature stages are arriving quickly; we won’t stop using them since a lot of them are really good and there is plenty of proof in the battlefield, but new and exciting markets will start to emerge, and you’d better be prepared. Staying up to date with the latest in JavaScript world isn’t easy, because of the pace of development, but there are some sources that can really help. First, the most important news source, in my opinion, is Echo JS, where you can an incredible amount of new content every hour. However, if you don’t have the time, the JavaScript Weekly newsletter is an excellent summary of the week in JS. Besides this, it is also important to keep an eye on the conferences around the world, and YouTube channels like, JSConf, React Conf, and Google Chrome Developers are wonderfully helpful. Conversely, if you’re interested in seeing some constructive critique of where JavaScript is heading, I recommend reading As a JS Developer, This Is What Keeps Me Up at Night by fellow JavaScript developer Justen Robertson.

15 Interesting JavaScript and CSS Libraries for April 2018

Our mission at Tutorialzine is to keep you up to date with the latest and coolest trends in web development. That’s why every month we release a handpicked collection of some of the best resources that we’ve stumbled upon and deemed worthy of your attention.

Radi is a fast and easy to use front-end javascript framework. It offers a simple way to build single-page or more complex applications. It is really tiny, only 3kb minified and gzipped, doesn't use any diffing algorithms or virtual dom, and requires no dependencies.

This is a JavaScript library for uploading any type of files. You can drop or copy and paste files, browse the filesystem or just use the API. It works with directories, local and remote URLs, and blobs. The library has a built in image optimization and automatic image resizing and cropping.

This is an open-source Bootstrap 4 Dashboard Theme. It is completely responsive, easy to integrate, follows the Bootstrap's coding conventions, and has a number of different customizable components to choose from. Tabler has great support for all modern browsers.

With Driver.js you can highlight items on your page, in order to attract the users attention. It is user-friendly, extremely lightweight and highly customizable. The library is licensed under MIT and works well on all browsers.

Rough.js is a lightweight canvas based library that can be used for drawing figures and shapes as if they were hand-drawn. It offers tools for drawin lines, curves, arcs, polygons and other shapes. The library also supports drawing SVG paths.

With this library you can print horizontal bar charts in your terminal. It is really simple to work with. You just need to pass an array in the command line, and the library will generate good lookin charts with legend and scale.

This is an open-source JavaScript library for creating beautiful charts for data visualization. It supports a large number of chart types such as bar, line, pie, heatmap and more. They are easy to use, highly customizable and work great on all browsers including IE8.

Material Design Icons is a simple, modern and beautiful icon set created by Google. It includes more than 900 icons, customized only with CSS. The icons are vector-based and look great on all screensizes, retina displays and low-dpi screens.

This is a modern, modular tool for compressing CSS files. It takes your CSS files and performs a number of optimizations, to compress your code as much as possible for a production environment. It removes whitespace, comments, unnecessary definitions and duplicate styles.

This is a JavaScript library for capturing keyboard input and key presses. It is very simple and user-friendly, has no dependencies and works on IE 6+, Safari, Firefox and Chrome. Special care must be taken when using it alongside other libraries, as it might interfere with keyboard handling.

The code is self-contained and you can copy-paste it directly in your project, and is available in CSS, Sass and Less. The effects may not work on older browsers, because most of them use CSS3 features like transorms and transitions.

Sympact is a minimal library for calculating the CPU and memory usage of tasks in Node.js. It executes a script and evaluates its execution time, CPU usage, and memory usage, then returns a report containing the averages of the results. In addition, it comes with a CLI for a better user experience.

First of all, nobody expected a lockdown. Nobody expected all the businesses will be paused or shifted to a total remote mode. And if most of the professions suffer from the lost opportunities and quarantine restrictions, developers (as they did so before for many years already) are the most used to ‘work from home’ people. And the new situation affected them not as much as others.

However, many of my friends working with aviation or travel, stayed without work. I hope, you all are ok.

I haven’t released March JS digest because of the start of the quarantine — I had a lot of work to do, and I suppose, many of you were busy with more important stuff than comparing and seeking for the best open source projects.

But now the situation is a bit better and I found some time to monitor what exactly had happened with JS repositories on GitHub in these two months, and what developers prefer for their projects when working from home.

Hence, we can grasp an overall situation and predict some trends to be followed in May. Stay safe!

We’re Looking For Someone To Lead FiveThirtyEight’s Data Visualization Team

FiveThirtyEight’s hallmark is that we use data to inform our journalism. There are other things that define us — empiricism, transparency, an outsider’s perspective and a little bit of irreverence. But when it comes down to it, data is at the core of our mission.

And often the best way to communicate that data is visually — with tables, line charts, histograms, scatter plots, interactive dashboards, combinations of all that, whatever this is and more. Data visualization is central to FiveThirtyEight, and we’re looking for someone to lead our graphics and interactives team, oversee data visualization for the site and contribute to our overall editorial direction. This is a big, important role — held by one of the most senior editors in our newsroom, someone who reports directly to the managing editor and works across departments.

More specifically, the Deputy Editor, Graphics and Interactives, (that’s what we’re calling this position) will:

Oversee a team of journalists — visual, computational and database — charged with creating data-driven interactive features and charts. This includes “big swing” interactive features and dashboards, as well as smaller-scale graphics, both interactive and static, on a daily and weekly basis.

Help to plan and execute FiveThirtyEight’s long-term journalistic priorities.

Supervise members of the interactives team to ensure career development and performance in line with team and organizational goals and priorities.

Refine FiveThirtyEight’s style for data visualizations, graphics and long-term projects.

Should you apply? Definitely … IF you …

Have at least seven years of experience working on a wide variety of high-quality, intuitive interactive features that present a lot of data in a manner that is easy to use and understand, or have at least two years of experience as a manager — either of a team of visual and interactive journalists or of a team with similar skill sets in a related field.

Are proficient in many of the following: dynamic programing languages (such as Python and Ruby), web development technologies (HTML, CSS, JavaScript), web frameworks (Rails), mapping tools (ArcGIS, QGIS), visualization libraries (WebGL, D3).

Have knowledge of at least one statistical language (R, Stata, etc);

Have a portfolio that demonstrates an understanding of storytelling on multiple platforms, particularly mobile, as well as a clean, elegant and sophisticated aesthetic.

It might seem like we’re asking for a lot, but a successful candidate will get to lead a team of some of the most talented and creative journalists around, as well as work at the center of some of the biggest stories in the months ahead — the 2020 election, March Madness, the women’s World Cup, the NBA playoffs, fights over health care and immigration policy, etc. It’ll be a fun job.

To apply, please go here.

ABC News and FiveThirtyEight are equal opportunity employers. Applicants will receive consideration for employment without regard to race, color, religion, sex, national origin, sexual orientation, gender identity, disability or protected veteran status.

The Top 3D JavaScript Libraries For Web Designers

Modern JavaScript is surprisingly powerful. Especially with support from WebGL libraries and SVG/Canvas elements.

With the right tools you can build pretty much anything for the web including browser-based games and native applications. Many of the newest groundbreaking features run on 3D, and in this post I’ve curated my list of the best 3D JS libraries currently available for web developers.

Three.js

There is no doubt that Three.js deserves to be at the top of this list. It can be somewhat complex to learn from scratch but it’s also one of the better 3D libraries out there.

It’s managed by a core group and released for free on GitHub. ThreeJS primarily works on canvas elements, SVG elements, and the WebGL library for rendering.

Learning the ropes is a challenge and will require at least mid-level JavaScript knowledge. But you can find the complete setup in the Three.js documentation.

If you’re serious about doing 3D on the web, this library is for you. It’s not the only choice, but it’s probably the most popular choice for a beginner to start building stuff fast.

Babylon.js

Another powerful library I like is Babylon.js. This one again relies on WebGL and runs solely in JavaScript.

It’s a bit more popular than other libraries but doesn’t have the same reach as Three.js.

Still it’s widely regarded as a powerful choice for web developers who want to create browser-based web games. On the homepage you can find a ton of demo previews and tips on how to get started with 3D game design.

There’s also a bunch of important links to resources like the GitHub repo and the Babylon JS tutorials.

All of those tutorials were designed by the Babylon team, so they’re an excellent place to start learning this library.

Cannon.js

For something a little off the beaten path check out Cannon.js. This doesn’t push the usual 3D concepts but instead works as a JavaScript-based physics engine for gaming.

Canon is meant to load fast so you can render elements quickly on the page. It supports most modern browsers and comes with a powerful API for building your own physics ideas off of this.

It works great with Canvas elements and with WebGL apps. The only tricky part is studying the library and getting over the initial learning curve.

Take a peek at the GitHub demos page to see how Cannon.js looks in the browser and why it’s so great.

CopperLicht

With a name like CopperLicht you might not know what to expect. But this is a powerful 3D JavaScript rendering engine built solely for web-based JS games.

Again it’s 100% open source and free to use for any project. The company that built CopperLicht does have some premium software & tools but these are not necessary for learning the CopperLicht library.

In fact, learning all the features will be tough since it supports an array of 3D functions like shadows/lighting, special effects, and 3D page element interactions.

The tutorials page is the best place to start and if you take this route be willing to take it slowly. There is a steep learning curve to get CopperLicht under your belt, although the payoff is well worth it.

Phoria.js

For web-based motion and 3D effects on the screen you might try Phoria.js. It’s really more of a graphics library but Phoria is rooted in 3D rendering inside HTML5 canvas elements.

The main site runs a bunch of demos and it’s a pretty reasonable library for creating 3D graphics. The learning curve isn’t too tough, and you’ll find a bunch of code snippets on the site that you can copy/paste.

Plus it doesn’t even use WebGL, so you don’t need to worry about that library. Although you will need to be comfortable working on the canvas element, but that just comes with practice.

Scene.js

For something that does run on WebGL check out Scene.js. Currently in version 4.2 this massive open source library lets you render elements in 3D for any modern browser.

It’s supported by a large team of developers and has years of major updates making it one of the best 3D rendering scripts you can use. However, this calls itself more of a visualization library, so it’s not just for rendering basic graphics.

Instead this could be used for much more complex tasks like designing multiple views of objects from different angles, or even creating basic 3D game graphics.

The homepage has a bunch of links to great examples if you’re curious to see how this works.

D3.js

While surfing the web you’ll often find charts and graphs that rely on 3D effects. Many of these run on D3.js which is a powerful JavaScript library for rendering data in 3D.

It’s also a totally free open source project with a very helpful GitHub page. The goal is to use SVG & canvas elements inside HTML to create dynamic data that can animate, rotate, and ultimately display information visually.

Take a look at the wiki entry on the GitHub page for more info. This includes some basic setup details along with documentation for anyone willing to dive into the D3 library.

LightGL.js

I don’t see much mention of LightGL.js around the web but it’s an excellent choice for 3D rendering in the browser.

This free open source library runs on the WebGL framework, and it’s meant to be the fastest, lightest library you can use. This works at a lower level than most abstraction libraries so it does require a stronger understanding of JavaScript.

Most developers just want simplicity so that could be why fewer people are sharing it around the water cooler.

But if you’re comfortable working in JavaScript then LightGL will give you a lot more control over your codebase.

Seen.js

For its complete lack of dependencies I had to include Seen.js in this list. Again this runs on the HTML5 canvas element but it works in vanilla JavaScript without any other required libraries.

It’s totally free for all developers and free to customize under the Apache 2.0 license. Some of the demos are pretty crazy considering they’re built solely in JavaScript.

Anyone who’s willing to push the boundaries of basic 3D visualization might take a look at Seen. It may not have a large following like Three.js but it’s a great canvas/SVG alternative that doesn’t rely heavily on WebGL.
