=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
