Have a look at the help pages for these functions in GOstats (you
will need the latest release version compatible with R-2.5.0):

     termGraphs
     inducedTermGraph
     plotGOTermGraph
     GOGraph

I think termGraphs would be a good place to start and then to see
about visualizing each connected component.  One of the challenges is
that it becomes difficult to visualize graphs with many nodes as the
labels get too small rather quickly.

I'm curous to know if these help and if you have suggestions of how
they could be more useful.

+ seth
