Charting Libraries

[Bill Vlahos]

Is anyone developing advanced charting libraries? I've used Ken Simon's 
charting object which is nice but makes simple 2D scatter and line 
plots. This has been fine for me but I have a college who really needs 
a much more powerful graphics library which would include many more 
chart types. In particular, he needs 3D charting (X, Y, and Z axis) 
with rotation, column, bar, and area charts.

I received an email awhile ago from someone I can't recall saying they 
were interested in building such an object.

We absolutely need this for Mac OS X but it would also be helpful if it 
ran in Windows.
