How to add a new chart type to dc.js

This is a step by step description of how I extended dc.js with a new chart type. It is inspired by a wiki page by Thomas Robert. A Bullet chart Mike Bostock already implemented a bullet chart in D3.js. The vertical version from Jason Davies uses the official code which is available as a d3-plugin. (I have submitted a proposal for a bug fix and will use it instead.)
