I've been playing with some Google Chart classes over the weekend and I've decided to give the code an early release to see what people think. It's all very basic still, I've mainly concentrated on implementing a flexible system, which I think I've achieved pretty well. I haven't done any performance tuning or anything (and there are a few places where performance improvements are obvious). This may be downloaded from TalkPHP.com. As well as an example on how to use it from within your PHP applications.
