Well, one reason I haven't included anything like that is because I'm
not sure what to write, or where to put it!

If you're using FGL graphs, you probably want [graphToDot]; otherwise,
[graphElemsToDot] might do what you want (for which I've written an
[example], which is also linked to from the [FAQ]).

[graphToDot]: http://hackage.haskell.org/packages/archive/graphviz/2999.13.0.1/doc/html/Data-GraphViz.html#v:graphToDot
