I’ve always loved making games. Board games, role-playing games, computer games— I just love abstracting things into rules, numbers, and categories. As a natural conse- quence, I’ve always loved data visualization. Damage represented as a bar, spells repre- sented with icons, territory broken down into hexes, treasure charted out in a variety of ways. But it wasn’t until I started working with maps in grad school that I became aware of the immeasurable time and energy people have invested in understanding how to best represent data. I started learning D3 after having worked with databases, map data, and network data in a number of different desktop packages, and also coding in Flash. So I was nat- urally excited when I was introduced to D3 , a JavaScript library that deals not only with information visualization generally, but also with the very specific domains of geospa- tial data and network data. The fact that it lives in the DOM and follows web standards was a bonus, especially because I’d been working with Flash, which wasn’t known for that kind of thing. Since then, I’ve used D3 for everything, including the creation of UI elements that you’d normally associate with jQuery. When I was approached by Manning to write this book, I thought it would be the perfect opportunity for me to look deeply at D3 and make sure I knew how every little piece of the library worked, while writing a book that didn’t just introduce D3 but really dived into the different pieces of the library that I found so exciting, like mapping and networks, and tied them together. As a result, the book ended up being much longer than I expected and covers everything from the basics of generating lines and areas to using most of the layouts that come to mind when you think of data visualization. It also devotes some space to maps, networks, mobile, and optimization. In the end, I tried to give readers a broad approach to data visualization tools, whether that means maps or networks or pie charts.
