DAG with all nodes ordered

[Re5dmsmXcG]

I have a DAG based on the partial order between the nodes. I give some total ordering of these nodes that is consistent with the partial order.

When I show the DAG, I want all the nodes to be on a line with the order that I give. Is there a way to do so in graphviz? (The following shows one example that I want).

Code: Select all

  -------
 /       \
/         V
o         o-------->o
\                   ^
 \                 /
  -----------------

Are you doing it for visualization of information diffusion/cascades? If so, I really want to know the answer for your question too =). Have you already figured it out?
