Yes, there certainly are. If you look in the Development category on Hackage, you’ll find tools for:
- graphing package dependencies — n.b requres older cabal
- graphing module dependencies
- graphing function calls
- graphing running data structures
In particular, SourceGraph contains many analysis passes, including:
- visualizing function calls
- computing cyclomatic complexity
- visualizing module imports
Other tools that you might be interested in are:
- HPC, for visualizing test coverage
- ThreadScope, for visualizing runtime behavior
- lscabal, extract modules from a package
Here is the functional call graph produced by SourceGraph run over cabal2arch:
