calligraphy (hackage): Calligraphy is a Haskell call graph/source code visualizer. It works directly on GHC-generated HIE files, giving us features that would otherwise be tricky, like type information and support for generated files. Calligraphy has been tested with all versions of GHC that can produce HIE files (i.e. GHC 8.8 through 9.4.) See the project's github page for more information.
