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.

That said, they're common enough that knowing how to make them is an incredibly useful skill as anyone doing data visualization work will at some point be asked for one.

D3's pie chart layout resides in the d3-shape package and is somewhere between the layouts of the last chapter and the line generators of Chapter 3, Shape Primitives of D3. We create a pie chart layout and pass it an array of numbers and then pass that to an arc generator to create our pie chart. Let's get to it.

We start by filtering out people who have less than 60 minutes of screen time and creating a pie generator...
