This is possible. GraphPlot adds additional functionality to the graphics function Text. Instead of a position, you can give an integer that corresponds to a graph node number. I used that functionality in this package: http://bond-graphs.googlecode.com/svn/trunk/BondGraphs/BondGraphs.nb Take a look at the definition of BondGraphPlot, specifically the option for VertexStyle that is fed to GraphPlot. I personally have a hard time making Mathematica 5.2 draw nice directed graphs. It certainly isn't a replacement for Visio. On the other hand, neither is Graphviz. 1. It is difficult to specify that the arrows between nodes should end or begin at a non-circular a bounding box border. 2. It would be nice to see more options for the node layout algorithms & edge routing.
