I work on a graph-based library and regularly generate DAGs for analysis and debugging. I have been using graphviz/dot but it's just so damn frustrating. You have to jump through hoops to get the layout right. It would be nice if something as ubiquitous as graphviz had a dedicated rendering engine for DAGs which did moderately sane things like place root and tail nodes on the same rank without requiring me to figure out which nodes are and manually position them.
