I don't know how pretty, but you can judge for yourself.

I'm trying to improve this, help is welcome. As it stands now, i think it looks pretty good. Feel free to play with the colors/fonts.

update:
ya know, caching these chart images might be nice, so you can do a per month lookup, with the current month being dynamic of course .
update: i overheard jcwren say something in the cb, so i tweaked a little more (stuff in readmore)

=head JC Graph
This was written for chris, aka jcwren, the greatest isp on earth,
in response to
http://perlmonks.org/index.pl?node_id=171725
In particular, it was written to replace the baaad
php chart generation counterpart for use at
http://www.tinymicros.com/pm/index.php?goto=PlotChart&nodeid=10277
It mimicks the look pretty well, even though GD::Graph::bars3d
does/can not guarantee spacing between the bars and the text.
I say it looks pretty good. You can see for your self at
