Generate diagrams for Haskell code [closed]

Question

Is there something that is kind of a cross between graphmod and haddock? I want a diagram like graphmod showing dependencies/relationships, but I want to include additional documentation in the diagram.

Answer 1

Not an existing one. Here are the list of available Haskell visualisation utilities (at least those on Hackage):

• graphmod which you've already found: visualise module dependencies.

• prof2dot visualise profiling reports

• hs2dot visualise Haskell code

• vacuum (and related packages) visualises the data structures at run-time

• SourceGraph (disclaimer: this is mine) aims to provide different forms of visualisation of the call graphs and perform some analyses; haven't had much time to work on this lately though.

• graphtype is for comparing data types

It may be possible to use doxygen to generate documentation with visualisation, but a quick Google didn't reveal any work on providing support for Haskell in doxygen (and it would require different markup than what Haddock uses).
