Depending on your requirements you might like to look at the GraphViz
(http://www.graphviz.org/) which is open source. While it may be
overkill for your specific task you could chop it down to what you need
and embed it or simply run it in an NSTask. It is capable of returning
a single page PDF file, which you can then simply load into an
NSImageView (possibly wrapped in an NSScrollView).
did the source to the pixelglow port of graphviz to OSX ever get released?
that might be handy... even though, as i recall, it tracked what is now a
slightly older version of graphviz.
you might also use the Framework that the builds of R for the Mac provide;
R has good social network mapping capabilities, including the bits to plot
graphs with opengl using various layout algorithms (kamada-kawai force
directed placement, circular layouts, fruchterman-rheingold, MDS-based
layouts, etc.)...... that's a little more work, i guess, to integrate --
but your results will be quite spectacular.
