pvpython cannot be used for interactive viz (generally), it mostly designed for batch. So it executes the script and then quits. Try adding a <div><br></div><div>raw_input()</div><div><br></div><div>at the end and the script will pause for input before exiting, giving you an opportunity to look at the rendered result. Generally you'd edit the script to add WriteImage() or somethign similar to generate screenshots or save processed data out.</div>
