Hi,

I have a graph that has subgraphs. Now when i have to autolayout this, I
first create a CompoundDirectedGraph with subgraphs as the top level
nodes. Now these subgraphs also have nodes that have connections to other
nodes.

An example would be a Entity Relationship diagram. The ER diagram has
entities which are connected to each other. and then there is primary key
- foreign key relationships which have to be denoted for each column. So
there are basically 2 types of connections:

1. Those connecting the entities (Polyline connection with bendpoints).
2. Those connecting the columns in the entity table(Polyline with
manhattan router).

Can someone please point how i can achieve autolayout on this kind of
graph.

Thanking u,

Ravi Ranjan.

In our application, we didn't use the built in features; we wrote a
wrapper around an external application (GraphViz dot) to perform the auto
layout for our visual notation.
