That's really nice! I like graphviz layouts because they use curved arcs (that sometimes make graphs look much better). How difficult would be to use it with d3?

The relevant algorithm is Sugiyama, and there's an unmaintained, but working plugin for d3 called dagre-d3.

Cool, I'm totally new to d3, but it seems very very interesting. It's nice to know that a good layout plugin is available. Thanks for the info!
