jsxgraph is also very nice:

http://jsxgraph.uni-bayreuth.de/wp/

Protovis is also very nice (as Barry said):
http://vis.stanford.edu/protovis/
examples: http://vis.stanford.edu/protovis/ex/

I believe that Protovis is based on SVG only, so it may not run in older
IEs. IE9 should work fine though. JSXGraph renders to either SVG or VML
(for older IEs).
