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


Despite the near mythical power of D3 layouts, they turn out to be nothing more than helpers that turn your data into a collection of coordinates. We've used the hierarchical layouts to create a boatload of different charts, without much more than a few lines of code differing between implementations.

These charts are so simple, we could have really extended our base object a lot to be far more abstracted; so by doing things such as fixating colors and adding the legend during the init() method -- between chapter6/index and common/index -- we've added probably around 600 lines, and we could probably reduce that by a couple of hundred. However, it's also useful to create each chart separately to reinforce the workflow needed by the hierarchical layouts, as I've done in this chapter.

In the next chapter, we'll look at a few more layouts. They'll look pretty familiar to the hierarchical ones in terms of how we write them, but we'll be flipping around the data a fair bit more to accommodate...
