[BioC] cant draw GO graph labels

[Michael Pheasant]

Hi,

I'm experimenting with using GOstats, trying to draw graphs with
Rgraphviz. If I follow the example in oneGOGraph.html I get a graph
which is just circles and arrows, but no labels on the nodes. 
The plot functions gives warnings "Label GO:0003680 is too large for
node in: drawTxtLabel ..." as below.

Does anyone have any suggestions as to how I could get labels on the
graph ?

Regards,

Mike Pheasant.
