Rgraphviz is a fairly complete interface that works on all systems now, 
including Windows.

but not the absolute latest Graphviz (2.4) as it has gone through pretty 
extensive code rearrangements. We should have a version for Graphviz 2.4 
in the next few weeks.

>>Dear all; I would like to draw a graph with vertices and edges, and I guess tcl/tk would be appropriate. I don't know tcl/tk but have googled for a 10-page (or so) introduction to 'getting started with tcl/tk in R' but without any luck.
