I hope that some friendly competition can spur both of us to deliver
even better tooling :)

Visualizing every aspect is probably never a good idea. At the moment
I'm sketching on alternative visualizations where only relations
between modules show up or where the data constructors for data types
aren't visualized.


On a related note: has anyone yet tried to visualize the flow of the
IO monad in an application?
