A lovely reader wrote in to tell me about MathIllustrations and GeometryExpressions, two $59 programs for Windows and Mac that put a math-specific spin on vector art. Both have free (though limited) demos. MathIllustrations might be the one last piece I need. From time to time it is necessary to generate a graph of a function. My school issued PC comes with TI-InterActive! for this purpose, but the results are low-res and it's Windows only. OmniGraphSketcher is a nice $29 app that makes pretty graphs, but they have to be hand drawn. You can't feed it an equation and have it figure out all the points. Also, no polar grids.

Both programs allow you to output .PNG files for later playing with in Fireworks.
