Who this book is for

This book is carefully designed to allow the reader to jump between chapters based on what they are planning to get out of the book. Here is a brief guide to help you navigate the book:

Every chapter is full of pragmatic examples that can easily provide the foundation to more complex work. We have explained, step by step, how each example works. That said, we also firmly believe in "learning by doing". As you work through the examples, continue to experiment with the sample code provided. Change the data. Change the scaling functions and colors. See how the map reacts and play with D3. Most importantly, have fun!
