Hi!

I want to layout a graph which has the following given specs:

- nr of nodes is about 30
- it contains 1 or more networks (its not a connected graph)
- nodes should be layed out in rows
- which node goes into which row is given
- the order of the nodes in columns should be arranged by layout algorithm in such a way that the layout contains no crossing of the connections

Something like this:

  A
 /|\
B C D
  |/
  E

Can this be done using DirectGraph and DirectGraphLayout?

I tried to understand the GEF FlowExample but I cant see how I can implement my constraints (assginment nodes to rows)
