GitHub user data
We will build a single-page application that uses, as its backend, the API developed in the previous chapter. The application contains a form where the user enters the login name for a GitHub account. The application queries the API to get a list of repositories for that user and displays them on the screen as both a table and a pie chart summarizing programming language use for that user:
