Do you know if King and Launchbury's implementation (Data.Graph) scales

None. I've built my own representing the graph as a hash table with
nodes as keys and arrays of nodes as values, and I'm using ruby's hash
and array classes (which are written in C) for that.

Did you have a look at igraph [http://cneurocvs.rmki.kfki.hu/igraph/]?
It would probably be a lot of work to bind to it (it has many public
functions), but it looks nice and has bindings for a few languages.
