> So "computational graph" as I understand it, just stresses the point that what is represented is a unit of computation (a.k.a. an automaton a.k.a. a grammar a.k.a. a language etc. etc.) rather than some other kind of graph.

Exactly. I think that the fact that the nodes represent a unit of computation is enough for it to be different from normal graphs I think.
