[Chicago] Drawing DAG in networkx

[Oren Livne]

Unfortunately, networkx.pygraphviz_layout(graph) is also extremely slow. 
Why is a such small DAG taxing on those layout programs? One 
topologically-sort nodes and place them accordingly fairly quickly. Can 
I supply an initial guess (=guide) for node positions to the layout 
calls? Doesn't seem like it from the docs.

Thanks,
Oren
