Overview of this book

Want to get started with impressive interactive visualizations and implement them in your daily tasks? This book offers the perfect solution-D3.js. It has emerged as the most popular tool for data visualization. This book will teach you how to implement the features of the latest version of D3 while writing JavaScript using the newest tools and technique You will start by setting up the D3 environment and making your first basic bar chart. You will then build stunning SVG and Canvas-based data visualizations while writing testable, extensible code,as accurate and informative as it is visually stimulating. Step-by-step examples walk you through creating, integrating, and debugging different types of visualization and will have you building basic visualizations (such as bar, line, and scatter graphs) in no time. By the end of this book, you will have mastered the techniques necessary to successfully visualize data and will be ready to use D3 to transform any data into an engaging and sophisticated visualization.

Shape Primitives of D3


In the last section, we made an explanatory graphic that used interaction to guide the user through the data. Often, however, the goal is just to make a dataset interactive and give the user some way of manipulating it, in other words, an exploratory graphic.

D3's behaviors save a boatload of time setting up the more complex interactions in a chart. Additionally, they're designed to handle differences in input devices, so you only have to implement a behavior once to have it work with both a mouse and touch device. The two currently supported behaviors are drag and zoom, which will get you pretty far.


Instead of having the user click buttons in the last example, what if we just let them drag the chart area to see the UK's prison population change? It involves a bit more work on the user's behalf, but it also gives them the ability to freely navigate through the chart, which may be desirable in some circumstances.

Let's extend our prisonChart object again. Comment out everything...
