Chapter 14. Visualization with D3 and the Play Framework

In the previous chapter, we learned about the Play framework, a web framework for Scala. We built an API that returns a JSON array describing a user's GitHub repositories.

In this chapter, we will construct a fully-fledged web application that displays a table and a chart describing a user's repositories. We will learn to integrate D3.js, a JavaScript library for building data-driven web pages, with the Play framework. This will set you on the path to building compelling interactive visualizations that showcase results obtained with machine learning.

This chapter assumes that you are familiar with HTML, CSS, and JavaScript. We present references at the end of the chapter. You should also have read the previous chapter.
