You simply have the URL of the image generation code in the <img> tag.

<img src='http://myserver.com/mygraphmaker.py' />

Of course, you might need to include a query parameter in there if the
image code needs some parameters....  You could also make javascript
calls to do the same thing.

There is not a way to print the buffer directly to the page.
