Ok. I see your DotEdge has explicit from/to nodes but not
language-dot. I've not a lot of code, so using your package should be
easy. But still I wonder what the intended usage of languge-dot is.

Exactly. Also, if I write only [EdgeStatement  [NodeId 2, NodeId 3]],
it will produce
-> 2 -> 3 (i.e. no 1, but sill the arc to 2).
