NM graphs

Christoph Berg created some NM graphs, but has a problem with one of them where stuff overlaps too much.

I don't know neato at all, but I do know that there is a tool called 'springgraph', which supports a subset of neato syntax. Not much, but I think enough for the graphs he's using; and since springgraph calculates node distances dynamically, using an algorithm based on the number of connections, it might solve his problem.
