Good lecture on subject :

Other similar projects (you must look before lose time with GraphViz) :

Constraint-based diagram editor : https://github.com/mjwybrow/dunnart (Probably best one ! Awesome work ...)
OGDF - Open Graph Drawing Framework : http://www.ogdf.net/doku.php (Very good library, better than GraphViz !)
