Thanks for the pointer. Just to clarify:

So the library itself supports drawing these other types of charts?  
Can you steer me towards some sample outputs?

One thing I was most unhappy to discover was the lack of Unicode  
support in Google charts. Another is the lack of control over some  
colours (the arrow in the google-o-meter, e.g.) and labelling. When  
one wants to build an accessible website, these things end up breaking  
the deal.

BTW Bjorn has written a binding to libgd. Does Cairo have similar  
functionality, e.g. quizzing an image file for geometry info?
