There's this option too, some others:
http://matplotlib.sourceforge.net/
Then Sage actually has 3D stuff too e.g.:
sage.plot.plot3d.platonic.cube(center=(0, 0, 0), size=1, color=None,
frame_thickness=0, frame_color=None, **kwds)
to render a 3D cube centered at the origin with default side lengt
Yup, similar experience here. And graphing calculators have now been
promoted to the point where their importance is probably no longer
questioned ... which is too bad ...
There are many ways to graph python-generated computer data. I have dabbled
with many, but for various reasons I continue to
