This is great! There's a real shortage of good layout algorithms. Everyone pretty much gave up after Graphviz.

Although tbh I have come to the conclusion that automatic layout algorithms don't work very well for large diagrams and don't save you much effort for smaller diagrams.

What I really want is some kind of interactive editor that has a go, but lets me drag nodes into more sensible positions while maintaining all the arrows. Maybe this makes that easier given its support for specifying node positions?
