It seems that, apart from gitk, there are some tools built for displaying git commit graphs. http://stackoverflow.com/questions/1057564/pretty-git-branch... In terms of the final use of this I haven't digged enough yet. What seems pretty straight forward is the potential of directed graphs for dashboard graphic interfaces. If you could export the git data to JSON, it shouldn't be very difficult to implement with D3 the dinamic generation of SVG's views. This way you might have a chance of making the graph interactive. Example: you could click on a node to retrieve the complete data contained in it, highlight a branch... Otherwise the graph might end not being very usable in terms of information organization or retrieval. However I'm very much for making cool things and not caring too much about usefulness. This is already a cool thing, thanks for sharing.
