I've been using a package called pyvis for a while to help visualize general graph data, but it's been pretty limited in terms of exposed API for vis.js (which is what it renders in) so I've been working on a more general full featured wrapper in Python that uses a fast graph library backend.

My test project is to visualize the repository as an interactive graph. It builds the html template in under a second right now and I'm planning on trying to make it something you can use to generate interactive repo graphs with.

It's still very WIP, but I think it's fun so I wanted to share.

Also, you can double click any node to have it open the source on GitHub. My goal is to make it host agnostic so you can just slap a repo url in there and it'll generate a graph with properly formatted links. I've got all the components exposed though, so you can manipulate how the link is generated as needed.
