You want to write two views. One that displays the graph and the form and 
another that generates the graph. There are several options here:

1. You have a custom content object that stores the configuration from the 
HTML. During image generation, you simply use the data.

2. The HTML data is simply encoded in the image source URL and is used by the 
image generating view:

  <img src=".../graph.jpg?x-axis-max=20&..." />
