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.

What you need for this book

You will need a machine that is capable of running Node.js. We will discuss how to install this in the first chapter--you can run it on pretty much anything, but having a few extra gigabytes of RAM available will probably help you while developing. Some of the mapping examples later in the book are kind of CPU intensive, though most machines produced since 2014 should be able to handle it.

You should also have the latest version of your favorite web browser--mine is Chrome, and I use it in the examples, but Firefox also works well. You can also try to work in Safari or Internet Explorer/Edge, or Opera, or any number of other browsers, but I find Chrome's developer tools to be the best.
