been consumed with the idea for the worst programming language in the world. a lisp 2 with clojure syntax, bytecode interpreted. with goroutines. like janet written by a moron, like common lisp written by someone who hates themselves. hand rolled garbage collector that has to deal with all the intermediate objects from immutable types. im tagging like 11 bits out of every pointer, 3 on the small end and 8 suspended in the middle of the top 16, which is a violation of the geneva convention. none of those bits encode the type and im still boxing floats. pretty sure i worked out how to support special environments that compile to totally untypechecked machine code for fast math. came up with an inline assembly thing for it i might just expose to the user. i don't expect ill ever bother with networking
#mostly grew from a desire to make a garbage collector#it's pretty cool#heavily generational bc it expects the user to mostly use immutable data structures#so you don't have to scavenge most of the heap on most collections#and it can do the immutable section concurrently#with a write barrier it could do the mutable section also#just have to make it play nice with c bindings#gc and some of the instructions are basically done#been playing with syntax by hacking on an interpreter

What is Schema Markup (and How to Implement It)
Have you heard the words Schema.org, Schema Markup, Structure Data thrown around in conversation? Have they left you scratching your head, wondering what the heck your teammates (especially web developers) were talking about?
Well, you are in luck! We’re clearing the fog so you know exactly what they are, why they matter, (and can get more out of all that technical talk).
Let’s roll.
What is Schema Markup?
Search Engines work hard to understand the content of the page. That is where Schema markup comes into play.
Ryan MacKeller, in his “My Six Search Resolutions for 2018” infographic, had the best short and skinny definition of Schema, in my opinion:
"No matter how smart we think Google is, it still struggles to make sense of what a webpage is actually about. That's why there's schema markup. It's a form of metadata added to a website that tells the algorithm what it is drawing and how to categorize it. In December 2017, Google even launch an algorithm update that penalized websites without."
In other words, Schema markup, also known as structured data, is the language of search engines, using a unique semantic vocabulary. TopSpot SEM does a great job breaking down what is semantic vocabulary.
“At its basis semantic vocabulary is simply the ability to break down a sentence (in any language) into its varying parts. For example, while you may be able to interpret “mydogneedswater” as “my dog needs water,” a computer typically can’t. In the same way, schema markup uses semantic vocabulary to break down the language of the computer. In this case, the computer’s language would be its code.”
It is code used to more clearly provide information to search engines in order to understand your content. In turn, this helps provide users with better, more accurate information in the rich snippets that are displayed beneath the page title.
(Example of SERP with different Schema Types)
Some schema you may be familiar with and not even realize it are the rating/review, product/service (showing price or whether it is in stop), and news articles that appear directly in Google when you enter certain queries.
Depending on what platform your site is built on, there are a couple of ways to implement schema. For WordPress, for example, there are plugins you can install.
For other CMSes, depending on the type of language, it is either manually in the head of the page, or inline with the HTML.
It is so essential to search engines, schema.org, the website for schema markup, is actually the result of collaboration between Google, Bing, and Yahoo!. Something’s gotta be crucial if it brings competitors together like that!
Why Should Implementing Schema Markup Be So Important to Me?
Search results that have schema applied inform the user faster.
The user is able to see details of your page at a glance which help them decide whether to click through or move on to a more relevant one.
This information also helps your website rank better for all kinds of content types, get found, and in turn, get more clicks.
Recently I have been doing some research on a new dehumidifier for my basement, and before I started writing this article, I never really paid attention to all the details on the SERPs.
Learning more about schema, I started to pay attention to them more. Here are the search results from me looking at the Frigidaire 70 Pint Dehumidifier.
I was able to quickly see all the ratings for the dehumidifier, and if I was lucky to price it was going to cost me. Then, I wanted to go in further to see what people were saying about the dehumidifier. Many reviews were right there!
Keep in mind this isn’t an SEO hack, it’s a staple that helps search engines find and display your content.
The only way that schema can hurt you is if your competitor is using it and you are not.
According to Search Engine Land, by implementing schema, you could get a 30% increase in click-through rate.
At IMPACT, we implement a very basic schema to help with your company profile, such as logo, website URL, phone number, and social media profiles.
On blogs, we also implement the Article Schema markup that includes the headline, featured image, author, published date, etc.
What Types of Schema Markups Are There?
There are hundreds of different markup types because there are so many different questions people turn to search engines to answer.
You may ask yourself, well, are there certain schema that only works on certain search engines? Since the big search engines (Google, Bing, Yandex, and Yahoo!) are collaboration as we mentioned, the answer is no. All of them are looking for and reading the same information.
Here is an FAQ from Schema.org to explain further:
Q: Why are Google, Bing, Yandex, and Yahoo! collaborating? Aren't you competitors?
Currently, there are many standards and schemas for marking up different types of information on web pages. As a result, it is difficult for webmasters to decide on the most relevant and supported markup standards to use. Creating a schema supported by all the major search engines makes it easier for webmasters to add markup, which makes it easier for search engines to create rich search features for users.
Here are the 10 most common schema markups that are used.
1. Organization Schema Markup
The organization schema markup clarifies your company introduction, including official logo, contact info, location, and social profiles. This helps give you the short and skinny of a company right off the bat without having to dig around to try and find basics. It also makes it easier for people to find the information they need to contact you right away.
2. Person Market Schema Markup
The Person Market Schema shows information about an individual, such as name, birthday, address, education, and family members.
Google assumes that if you’re searching for someone by name, you’re likely looking for some basic information.
So, with this schema, it’s aiming to deliver the answer you seek without you needing to click through to another website.
3. Local Business Schema Markup
The Local Business Schema Markup is great for local companies or a local branch of an organization. It helps consumers find the company's location and other information such as the address, opening hours, contact info, etc.
Local Business is a particular physical business or branch of an organization, for example, restaurant, branch of a bank, bowling alley, medical practice, etc.
4. Product & Offer Schema Markup
The Product & Offer markups are used to sell a specific item of a service or product.
Both enable product information to be delivered, such as price and status, but the Offer markup also requires the price and price currency properties, while Product markup only requires the name property.
This helps your product/service stand out from the rest if competitors aren't using it, or it allows the users to easily compare you to other competitors if they are selling the same product/service you are.
5. Breadcrumbs Markup
Breadcrumbs markup lists the path links that lead to the current page. It helps users to see their location and helps reduce bounce rates.
6. Article Schema Markup
Schema Article Markup is most commonly used for news and blog posts.
It makes it easier for search engines to understand the content pulling in the headline, time it was published, a featured image, and sometimes even a video. There are, however, different types of Article Schema Markup for the different type of articles, such as Blog Post, News Article, and Scholarly Article.
7. Video Schema Markup
Video Schema Markup is a good way to help Google crawl and index videos on your website, as we all know it is tough for search engines to do so.
It also helps your video appear in the Google Video Search, alongside those from YouTube.
8. Event Schema Markup
Event Schema Markup provides additional information for scheduled events (i.e. webinars, concerts, lectures, etc) such as date, location, and price.
This helps make it easier to draw people to the specific events they’re looking for and give them the basic information they need to want to make a purchase.
9. Recipe Schema Markup
Recipe schema markup is meant for the recipe website pages to show as a rich snippet.
Besides making searchers hungry, it helps them evaluate the finished product before they click through.
10. Rating/Review Schema Markup
Who doesn’t look at reviews before they purchase a service or a product? Rating Schema Markup generates your best directly in the SERP pages.
This will help get useful buyer information right out front without the user having to dig deeper.
Looking for the full list of items that Schema Markups can define, you can find them here.
Schema Encoding Types
There are just three different encoding types of Schema Markup they are, JSON-LD, Microdata, RFDa. SEMRush does a great job breaking it down further for the average marketer to understand.
As a marketer, it’s important to understand that RDFa and Microdata are the older way to write schema.
These types of language involve implementing code right into the HTML and this can make things more difficult and more prone to causing issues on your page such as causing incorrect HTML syntax and your page not properly loading.
JSON-LD is the preferred method of adding structured data to your website because it is the easiest to understand as well as implement into the code of your site. Just until recently not all search engines adopted this type of language so you had to use the others.
RDFa stands for Resource Descriptive Framework in Attributes. It is a form of code that can be added to any HTML, XHTML, and XML-based document.
In the end, they all do the same thing for getting your schema out there for search engines, the only difference is how they are implemented into your site.
RDFa’s attributes include:
about - to specify the resource the metadata is about
rel and rev - to specify a relationship and reverse relationship with another resource
src, href, and resource - to specify a partner resource
content - to override the content of the element when using the property attribute
datatype - to specify the datatype of text specified for use with the property attribute
typeof - to specify the RDF type of the subject or the partner resource
Microdata implementation is similar to RDFa, and its attributes include the following:
itemscope - to create the item and indicate that the rest of the element contains information about it
itemtype - to describe the item and properties with a valid URL of a vocabulary (for example, “https://schema.org”)
itemprop - to indicate that the containing tag has the value of a specified item property (ex, itemprop=”name”)
itemid - to indicate a unique identifier of the item
itemref - to reference properties of an element that are not contained in the itemscope. This provides a list of element ids with more properties elsewhere in the document
JSON-LD stands for Javascript Object Notation for Linked Objects. This style of annotation can implement schema by pasting directly in the <head> or <body> tag of a web document. The notation uses “@context” and “@type” attributes to specify the vocabulary (schema.org).
Looking for a more technical definition of each (maybe for your developers) Google has a great definition of each.
How Do I Implement Schema Markup on My Site?
Now you have probably said to yourself, great another coding language I have to learn, or more money that I have to spend having a developer to get this implemented on my site.
That's not the case!
You don't need to learn any new coding skills!
Here are some steps you can take using some of Google’s tool to get your schema markup generated.
1. Go to Google's Structure Data Markup Helper.
2. Select the type of data that you plan to markup.
3. Paste in the URL of the page or article you want to markup.
4. Highlight and select the type of elements to be marked up.
5. Continue adding markup items.
Use the list of data items as a guide, and continue highlighting the other items in your article to add them to the markup list. Don’t worry if you can’t tag every item, just get the ones that are required. But keep in mind the more the better.
6. Create the HTML.
7. Use the Structured Data Testing Tool to find out what your page will look like with the added markup. You can also use the tool to test for any warnings.
8. Add the generated schema markup to your web page. If you wish you can also add before testing.
There are plenty of other tools out there that will help you create your schema markup, and even validate it.
Here are just a few.

Statistics
In 2014, 3,179 people were killed, and 431,000 were injured in motor vehicle crashes involving distracted drivers.
As of December 2014, 169.3 billion text messages were sent in the US (includes PR, the Territories, and Guam) every month. (CTIA)
Ten percent of all drivers 15 to 19 years old involved in fatal crashes were reported as distracted at the time of the crashes. This age group has the largest proportion of drivers who were distracted at the time of the crashes. (NHTSA)
Drivers in their 20s are 23 percent of drivers in all fatal crashes, but are 27 percent of the distracted drivers and 38 percent of the distracted drivers who were using cell phones in fatal crashes. (NHTSA)

Chapter 1. Introduction
Why Data Visualization?
Our information age more often feels like an era of information overload. Excess amounts of information are overwhelming; raw data becomes useful only when we apply methods of deriving insight from it.
Fortunately, we humans are intensely visual creatures. Few of us can detect patterns among rows of numbers, but even young children can interpret bar charts, extracting meaning from those numbers’ visual representations. For that reason, data visualization is a powerful exercise. Visualizing data is the fastest way to communicate it to others.
Of course, visualizations, like words, can be used to lie, mislead, or distort the truth. But when practiced honestly and with care, the process of visualization can help us see the world in a new way, revealing unexpected patterns and trends in the otherwise hidden information around us. At its best, data visualization is expert storytelling.
More literally, visualization is a process of mapping information to visuals. We craft rules that interpret data and express its values as visual properties. For example, the humble bar chart in Figure 1-1 is generated from a very simple rule: larger values are mapped as taller bars.
Figure 1-1. Data values mapped to visuals
More complex visualizations are generated from datasets more complex than the sequence of numbers shown in Figure 1-1 and more complex sets of mapping rules.
Why Write Code?
Mapping data by hand can be satisfying, yet is slow and tedious. So we usually employ the power of computation to speed things up. The increased speed enables us to work with much larger datasets of thousands or millions of values; what would have taken years of effort by hand can be mapped in a moment. Just as important, we can rapidly experiment with alternate mappings, tweaking our rules and seeing their output re-rendered immediately. This loop of write/render/evaluate is critical to the iterative process of refining a design.
Sets of mapping rules function as design systems. The human hand no longer executes the visual output; the computer does. Our human role is to conceptualize, craft, and write out the rules of the system, which is then finally executed by software.
Unfortunately, software (and computation generally) is extremely bad at understanding what, exactly, people want. (To be fair, many humans are also not good at this challenging task.) Because computers are binary systems, everything is either on or off, yes or no, this or that, there or not there. Humans are mushier, softer creatures, and the computers are not willing to meet us halfway—we must go to them. Hence the inevitable struggle of learning to write software, in which we train ourselves to communicate in the very limited and precise syntax that the computer can understand.
Yet we continue to write code because seeing our visual creations come to life is so rewarding. We practice data visualization because it is exciting to see what has never before been seen. It is like summoning a magical, visual genie out of an inscrutable data bottle.
Why Interactive?
Static visualizations can offer only precomposed “views” of data, so multiple static views are often needed to present a variety of perspectives on the same information. The number of dimensions of data are limited, too, when all visual elements must be present on the same surface at the same time. Representing multidimensional datasets fairly in static images is notoriously difficult. A fixed image is ideal when alternate views are neither needed nor desired, and required when publishing to a static medium, such as print.
Dynamic, interactive visualizations can empower people to explore the data for themselves. The basic functions of most interactive visualization tools have changed little since 1996, when Ben Shneiderman of the University of Maryland first proposed a “Visual Information-Seeking Mantra”: overview first, zoom and filter, then details-on-demand.
This design pattern is found in most interactive visualizations today. The combination of functions is successful, because it makes the data accessible to different audiences, from those who are merely browsing or exploring the dataset to those who approach the visualization with a specific question in search of an answer. An interactive visualization that offers an overview of the data alongside tools for “drilling down” into the details may successfully fulfill many roles at once, addressing the different concerns of different audiences, from those new to the subject matter to those already deeply familiar with the data.
Of course, interactivity can also encourage engagement with the data in ways that static images cannot. With animated transitions and well-crafted interfaces, some visualizations can make exploring data feel more like playing a game. Interactive visualization can be a great medium for engaging an audience who might not otherwise care about the topic or data at hand.
Why on the Web?
Visualizations aren’t truly visual unless they are seen. Getting your work out there for others to see is critical, and publishing on the Web is the quickest way to reach a global audience. Working with web-standard technologies means that your work can be seen and experienced by anyone using a recent web browser, regardless of the operating system (Windows, Mac, Linux) and device type (laptop, desktop, smartphone, tablet).
Best of all, everything covered in this book can be done with freely accessible tools, so the only investment required is your time. And everything we’ll talk about uses open source, web-standard technologies.
By avoiding proprietary software and plug-ins, you can ensure that your projects are accessible on the widest possible range of devices, from typical desktop computers to tablets and even phones. The more accessible your visualization, the greater your audience and your impact.
What This Book Is
This book is a practical introduction to merging three practices—data visualization, interactive design, and web development—using D3, a powerful tool for custom, web-based visualization.
These chapters grew out of my own process of learning how to use D3. Many people, including myself, come to D3 with backgrounds in design, mapping, and data visualization, but not programming and computer science.
D3 has a bit of an unfair reputation for being hard to learn. D3 itself is not so complicated, but it operates in the domain of the Web, and the Web is complicated. Using D3 comfortably requires some prior knowledge of the web technologies with which it interacts, such as HTML, CSS, JavaScript, and SVG. Many people (myself included) are self-taught when it comes to web skills. This is great, because the barrier to entry is so low, but problematic because it means we probably didn’t learn each of these technologies from the ground up—more often, we just hack something together until it seems to work, and call it a day. Yet successful use of D3 requires understanding some of these technologies in a fundamental way.
Because D3 is written in JavaScript, learning to use D3 often means learning a lot about JavaScript. For many datavis folks, D3 is their introduction to JavaScript (or even web development generally). It’s hard enough to learn a new programming language, let alone a new tool built on that language. D3 will enable you to do great things with JavaScript that you never would have even attempted. The time you spend learning both the language and the tool will provide an incredible payoff.
My goal is to reduce that learning time, so you can start creating awesome stuff sooner. We’ll take a ground-up approach, starting with the fundamental concepts and gradually adding complexity. I don’t intend to show you how to make specific kinds of visualizations so much as to help you understand the workings of D3 well enough to take those building blocks and generate designs of your own creation.
Who You Are
You may be an absolute beginner, someone new to datavis, web development, or both. (Welcome!) Perhaps you are a journalist interested in new ways to communicate the data you collect during reporting. Or maybe you’re a designer, comfortable drawing static infographics but ready to make the leap to interactive projects on the Web. You could be an artist, interested in generative, data-based art. Or a programmer, already familiar with JavaScript and the Web, but excited to learn a new tool and pick up some visual design experience along the way.
Whoever you are, I hope that you:
Have heard of this new thing called the “World Wide Web”
Are a bit familiar with HTML, the DOM, and CSS
Might even have a little programming experience already
Have heard of jQuery or written some JavaScript before
Aren’t scared by unknown initialisms like CSV, SVG, or JSON
Want to make useful, interactive visualizations
If any of those things are unknown or unclear, don’t fear. You might just want to spend more time with Chapter 3, which covers what you really need to know before diving into D3.
What This Book Is Not
That said, this is definitely not a computer science textbook, and it is not intended to teach the intricacies of any one web technology (HTML, CSS, JavaScript, SVG) in depth.
In that spirit, I might gloss over some technical points, grossly oversimplifying important concepts fundamental to computer science in ways that will make true software engineers recoil. That’s fine, because I’m writing for artists and designers here, not engineers. We’ll cover the basics, and then you can dive into the more complex pieces once you’re comfortable.
I will deliberately not address every possible approach to a given problem, but will typically present what I feel is the simplest solution, or, if not the simplest, then the most understandable.
My goal is to teach you the fundamental concepts and methods of D3. As such, this book is decidedly not organized around specific example projects. Everyone’s data and design needs will be different. It’s up to you to integrate these concepts in the way best suited to your particular project.
Using Sample Code
If you are a mad genius, then you can probably learn to use D3 without ever looking at any sample code files, in which case you can skip the rest of this section.
If you’re still with me, you are probably still very bright but not mad, in which case you should undertake this book with the full set of accompanying code samples in hand. Before you go any further, please download the sample files from GitHub.
Normal people will want to click the ZIP link to download a compressed ZIP archive with all the files. Hardcore geeksters will want to clone the repository using Git. If that last sentence sounds like total gibberish, please use the first option.
Within the download, you’ll notice there is a folder for each chapter that has code to go with it:
chapter_04 chapter_05 chapter_06 chapter_07 chapter_08 …
Files are organized by chapter, so in Chapter 9 when I reference 01_bar_chart.html, know that you can find that file in the corresponding location: d3-book/chapter_9/01_bar_chart.html.
You are welcome to copy, adapt, modify, and reuse the example code in these tutorials for any noncommercial purpose.
Thank You
Finally, this book has been handcrafted, carefully written, and pedagogically fine-tuned for maximum effect. Thank you for reading it. I hope you learn a great deal, and even have some fun along the way.

I considered making the campaign rely heavily on data visualisation because I thought that it would be good way to get statistical information across well to our target audience. This is because instead of communicating statistical information through potentially intimidating large blocks of text I wanted to use data visualisation to communicate to my audience through simpler visual means. We ultimately didn’t go along with this idea because my partner wasn’t enthused by the idea. I did draw a few starter ideas for what the ultimate results might look like.
