Long-time Icon developer Clinton Jeffery gave a presentation on this
topic at PyCon 2005:

    Profiling and Visualizing Python Program Behavior
<http://www.python.org/pycon/2005/papers/49/PyCon2005ProfilingandVisualizing.pdf>

It was a delight for me to meet him there, since I was an Icon
programmer before Python existed ;-)  He had some impressive
preliminary CPython visualization results, which required (a) a lot of
work, and (b) some modest changes to the core interpreter.  Alas, I
haven't heard more about it since then.  If I were you, I'd ask Dr.
Jeffery what became of that project.
