PS  I'd recommend doing this in gnuplot or pgfplots or some other
scripting graph language:
1) if we have a great way to visualize the bug history, it could
be useful for other releases
2) if might be useful for other projects
3) we might want to add extra overlays (e.g. yellow vertical lines
for important dates like release candidates or when Phil started
checking regtests?)
4) it might be good to subtly change the color of each line.
Like, shifting from light green-blue to light blue-green over the
course of all 148 lines?  or maybe adding a bit of red to each
line, corresponding to the number of days it took to close that
bug?

Scientific visualization is an art unto itself; I could easily
spend 3 hours just to produce one really good graph.  Exactly what
to plot, what shades of colors to use, etc etc... fun times!  :)
