Hello,
Has anyone got some code for drawing charts?
I don't mean graphs of functions, ala
http://dockerz.net/twd/HaskellCharts
and I don't mean calls to the Google Charts API ala

I'm not sure it's what you're looking for but it could probably be used as a

Hi
Give the following code below, my question is - how do i setup a
dependency of User on Common?
Perhaps a first attempt should not have Common store a reference to User,
nor User store a reference to Common. Instead, have two Data.Map.Map's: one

I think. I put the code in the Haskell wiki:
