This 6.x release is intended for new features of this module only. Some things that would be a good idea to add, but which have not yet been implemented:
1. Converting the graphs from using JavaScript to being true images. This is a major rework.
2. Add more administrative features (like removing images cached from nodes that no longer exist, or for whom the equation no longer exists.
3. Perhaps some simple mathematical replacements (like random numbers and simple calculations?)
