I maintain the Chart library:

     http://hackage.haskell.org/package/Chart

I'd like to see it used more widely, but gtk/cairo seems to be a problem 
for many people.

Is the cairo dependency the reason you are suggesting that an 
alternative plotting library be built?
Is your problem with cairo the difficulty in setting it up on ms 
windows/osx?
What graphics API would you suggest using to "render in a window from ghci"?

If there were a good cross platform alternative to cairo, I'd happily 
target this additional 2D drawing API. However, I don't think there 
currently is one. Neither gloss nor the diagrams library currently have 
adequate text support.
