A quick grep through the source of the graphs/ directory doesn't show any calls to dot, neato, or circo. I've used the "graphviz_to_file_named" method to save out a graphviz file, and then run dot/neato/whatever from the command line. I would *love* to have "layout='dot'", "layout='neato'", etc., options to the graph plotting which would use the graphviz optional spkg if installed. Right now the graphviz_to_file_named method doesn't seem to support edge colors, etc., so it would be fantastic if all of the graph plotting options worked as well.
