Allow HMMs to be diagramed

It looks like currently nodes that connect back to themselves are ignored. A curve line segment should be drawn with the arrow pointing back to the node.

Assuming HMM means Hidden Markov Model, I think this is a good idea.

You can draw a HMM as a PGM using daft:

Are you thinking about a transition diagram, showing the relationship between values of the state instead of the dependence/independence between random variables ?
