I have a list of timestamps representing how long it takes a process to
finish under different conditions. I also have a summary of the stages that
process goes through. It is way too many numbers to make sense of them
without some kind of graphical representation. 
I get all these information out of Haskell simulator. Therefore I would like
to be able to do two things in Haskell:
1) analyze the data (mean, std dev etc) - that's the easy part and I more or
less know how to do it in Haskell
2) display result of the analysis (pie charts, histograms, plots)
