The library at the above URL supports a range of backends through the
(nice to use) cairo graphics API. In memory images are supported. Also,
it's by no means just graphs of functions - that just happens to be

An the moment it does line charts and a few variants of these. I'll add
pie and bar charts when I need them - patches in the meantime gratefully
accepted.
