SourceGraph looks pretty interesting. I don't think the output is that bad, though. (If anyone is curious,
attached is a tarball of what SourceGraph generates for XMonad.)

But I do have one or two problems:
1) Didn't mention that it uses some executable 'dot', which Graphviz provides.
2) Fails on XMonadContrib? While SourceGraph on XMonad finished in 1 or 2 seconds, SourceGraph
xmonad-contrib.cabal has been running at 99% CPU (only one CPU - I wonder if it could be parallelized) now
for something over 3 hours. I know XMC is a bigger codebase than XM, but it's not thousands of times bigger! :)
