You may wish to start here:

  http://viewcvs.sourceforge.net/
  http://cvsplot.sourceforge.net/
  http://www.red-bean.com/cvs2cl/
  http://www.akhphd.au.dk/~bertho/cvsgraph/

Some of the stuff that viewcvs can add to a MySQL database will be of
interest to you.

Feel free to contribute if you add things like this.

Well, diffstat has problems getting lost in changes to files that have a
'-- ' leading comment prefix and does not understand the '-p'
annotations, so you may want to normalize your diffs using something
like one of the patchutils programs.
