There are two code bases you would need, both in python it seems. The first is the visualization itself, and the second is the code that takes a full repository dump and parses it into a normalized postgres database. I actually wrote the latter, with a nod from the professor that paid me some poor undergrad research wage to create it, I could probably publish it.
