My current plan is to generate this kind of graph from documentation pages, similar to what I did with Wikipedia. The dynamic I thought was loading new pages as I open nodes (the same way you can visit the whole Wikipedia by clicking links, you'd be able to open all Wikipedia graph by expanding nodes). I also thought about showing the evolution of the graph over time, like gource.io. But if you are thinking about a real time update that doesn't require a page refresh, it's not in my plans no.
