Summary


This chapter provided a quick introduction to data visualization topics and introduced Chart.js, the JavaScript library with which you will learn to create responsive interactive visualizations for the web. We also demonstrated how standard web technologies provide all you need to create charts for the web, and how a data visualization library such as Chart.js can be beneficial.

In the next chapter, we will cover the fundamentals of some standard technologies used by Chart.js—data formats and data manipulation techniques—but if you want to start using Chart.js right away, you can skip it and jump straight to Chapter 3, Chart.js – Quick Start.
