Koen,

There is a patch to pybootchartgui that allows visualization. RP has
the patchset IIRC.  I'm going to be working on buildstats
visualization soon and I'm leaning towards using jquery/flot to create
a way to allow end users to generate via browser some comparative
graphing of buildstats against different builds/statistics. This way I
can set it up for the AB to compare all the builds we're doing there
and end users can just use it through a browser either locally or via
a server.
