A more thorough explanation and example on how to make a D3.js line graph

This is actually the accompanying presentation I gave to our lab a few months ago on how to make the line graph in d3.js that I posted earlier. It's intended for the lab audience (people who know how to program and use the command line but have no experience with making a web page). Hopefully it'll be helpful to others.

The repo link for the accompanying example is at BitBucket.
