Hello there,
I'm writing a small framework to analyze SVN repositories.
It's a very simple architecture based on plugins, at the moment they generate different comma-separated value files, which can be easily visualized using GnuPlot/Excel/R/Matlab/...

For example the 'activity_overview' plugin produces a list of entries in the following form:
<RevisionNumber, Author, Date, ListOfChangedFiles, NumberOfDiffLines>

It would be really cool to implement a simple visualization with Processing, however i don't think i will have the time to do so, since i never used it.
I have a couple of ideas but i'm of course open to new ones.

If you're interested in creating such a plugin, please let me know!

All i have to offer is some fame (the project will be on SourceForge soon) and maybe the possibility to be cited in the context of a scientific publication.

P.S. I'm probably going to include code_swarm plugin too http://vis.cs.ucdavis.edu/~ogawa/codeswarm/
