Try this:
$ python antisulk.py > p.html
and see whats in there.

-------- antisulk.py --------------------------------------

def myFunction(x):
    import math
    return math.sin(x)

This is for Chris Lyon who just wants to plot a graph
on a webpage.  I can't help you with linux.  Actually I
quit linux myself because of all those configuration
problems over and over again.  But how about plotting a
graph on a webpage *without using images*?  If you hold
the mouse over the graph it shows you the coordinates
in a popup help window.  Well, at least it does with my
IE6 browser.  Have fun with CSS !
