Simple line graph in d3.js

This is a simple line graph designed to allow investigation of aspects of using d3.js and is used as a teaching aid.

It is the baseline example graph used in the D3 Tips and Tricks book.

Edit: June 2014

I am going through a process of updating the code resources for the book and the latest (but not particularly different) example of this graph is here.
