> I commented out the import pylab as pl because I couldn't get the matplotlib.pylab import working.  So, anyway, I hit F5, and it seems to run, but it doesn't really do anything.  Isn't this either supposed to be downloading data from the web, or throwing an error so I can troubleshoot, and try to figure out what's going on?  It's hard to troubleshoot, when you don't get any error.  Does this work for others?
