I am a newbie to the dot layout in graphviz. I am trying to specify a graph in the dot language, and I want certain sets of nodes to be forced to overlapped by a certain amount (say 70% of their area or something with that effect). I know I can force the x and y positions of nodes and thus induce overlap, but in this case, I am writing a C# program that given certain input spits out the relevant dot script for the graph, so the number of nodes, etc are not hardcoded and so I can't come up with a scheme to hard-code x and y positions of all nodes. Any help in this will be greatly appreciated!
Thanks a lot!
