I have not seen any other places where edges from a higher to a lower node go up.
dot was run with the default parameters, with gif as the output format.
Input file: b84.dot
Adding a couple of hundred more nodes seems to result in dramatic slowdowns. The program that generated this file can easily create output with hundreds of thousands of nodes and edges.
Hows the progress with SVG coming along?
Very nice work!
