D3.js: a simple graph

About this episode

This episode is the third episode in the D3 series and a continuation of thinking-with-joins. In this screencast we start playing around with some of the graphing goodness D3.js offers.

A recap of what was mentioned

Like before, we'll be working in the draw() function which is a common pattern in the D3 world. Everything in draw() gets removed and the function is plugged directly into the d3.json call.

A previously used json file is used in this screencast again. It is a basic json file that contains a title as well as a value. These values will be used to give each bar a percentage value
