By "diagram" do you mean "chart"? If so, use BLT (which I think only binds 
with Python or something).

If you actually mean a diagram, like a graph, with circles and arrows, try

Updating it in real-time should only require a little work. I have 
bench-versions which do that, so if you actually need it ping me privately.
