Subject: graphing/charting application

I'm hunting around for a simple application that generates images like
bar graphs.  PNG output would be ideal.  I just need to create a chart or
two, so I'm not sure that learning the API for a new library and writing
software is exactly what I need.

Is there something in gems that'd suit my needs?  I'd be perfectly happy
with something that just takes a series of numbers and strings as input
and dumps an image file.  My preference would be for a 3D-looking chart
(with those faux-3D verticle bars in many a PowerPoint slide, for
instance), but 2D is acceptable as well.  In addition to helping with my
current need to generate a couple of visual aids, such a thing might also
provide some useful hints on how to accomplish similar tasks in the
future when I look at the source code -- which is one of the reasons I'd
like to find something written in Ruby.

Any help is appreciated.
