I have 3 compound(parent) nodes. In every compound node there are 3 child nodes. I want the layout to be exactly like this:
COMPOUND1 COMPOUND2 COMPOUND3
node1.type1 node4.type2 node4.type3
node2.type1 node4.type2 node4.type3
node3.type1 node4.type2 node4.type3
so I want to have 3 compound nodes in one row and in each of them one column of nodes each on top of each other. There are edges between different child nodes but I guess this is irrelevant.
