I'm creating GraphML programmatically and then using the hierarchical manager in YED to create a readable diagram. (The result is excellent!). However, there are some node types I would like to exclude from the initial hierarchical repositioning.
Are there any properties/attributes one can set in GraphML that cause node exclusion? Or is my best strategy simply to place those nodes in a particular geographical area of the diagram and exclude them by selection before applying the layout manager?
