Re: [Haskell-cafe] language-dot usage

*Shameless plug* use my graphviz package!

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.

OK, relevant answer:

I'm wondering how to make edges. I was expecting to generate something like

1 -> {2 ; 3}

but get in fact

1 -> 2 -> 3

I used the (pseudo) statements

[NodeStatement $ NodeID 1, EdgeStatement [NodeId 2, NodeId 3]]

So you're wanting an edge from 1 to 2 and from 1 to 3, but getting from 1 to 2 and from 2 to 3 instead?

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). Thanks, Thu
