Too slick to be useful to me – Instaviz Review

The programmer has won prices for his slick work on Mac OS X and graphviz. The problem is that in trying to replicate that he has gone further and not allowed to configure the program. In my case I am a pure mathematician whose speciality are undirected graphs. The ones I draw are very complex and having to go edge by edge to make them undirected is a colosal bore. Added to doing the same for every vertex that is not a circle adds to the frustration. I can't use it when I'm teaching to draw graphs on the fly as I have to go and tweak every edge. I wish there was at least a setting for the default type of edge.
