Thanks very much! Yea, with .dot, the layout engine decides where things go. So, the agent doesn't know what the result looks like, leading to render, look, fiddle loops. And, depending on how much you care about layout, .dot might not give you enough knobs to turn to make it look like what you want.

The idea with Reladraw is that a human or agent could just state "I want this node to the right of this other one", rather than have a layout engine decide. Hopefully less fiddling for agents!
