I think you should write a processor. You could add a parameter which sort
of output the user would like to get. The processor could either include
the HTML or an image tag. Perhaps you will need an action to access the
image, if you don't want to simply attach it.
As this processor is relative time consuming you should use caching. see
This processor could be extended to a parser later, to allow pygantt
