In this chapter, we gave a working definition of data visualization, one of the main fields of application of the D3 library.

This book is about D3 and how to create interactive data visualizations in real-life settings. We will learn about the inner working of D3 and create well-structured charts to be used and shared across projects. We will learn how to create complete applications using D3 and third-party libraries and services as well as how to prepare our development environment to have maintainable and comfortable workflows.


Learning D3 may take some time, but it's certainly rewarding. The following chapters are focused on providing the tools to learn how to use D3 and other tools to create beautiful charts that will add life to your data.
