Statically analyse Haskell source code using graph-theoretic techniques. Sample reports can be found at: http://code.haskell.org/~ivanm/Sample_SourceGraph/SampleReports.html

To use SourceGraph, call it as either:

SourceGraph path/to/Foo.cabal

Or, if your project doesn't use Cabal, then there is limited support for using an overall module from your program/library:

SourceGraph path/to/Foo.hs

Note that the Cabal method is preferred, as it is better able to determine the project name and exported modules (when passing a Haskell file to SourceGraph, it uses that module's name as the overall name of project and assumes that it is the only exported module; as such, it works better for programs than libraries).

Whichever way you run SourceGraph, it then creates a SourceGraph subdirectory in the same directory as the file that was passed to it, and within that subdirectory creates the analysis report in Foo.html .

SourceGraph is still experimental in terms of its ability to parse and properly understand Haskell source code and in the types of analyses it performs.
