Class RadialTreeLayoutManager
The RadialTreeLayoutManager is a specialization of the DirectedTreeLayoutManager and employs a circular layout algorithm for laying out the diagram nodes. The RadialTreeLayoutManager positions the root node at the center of the graph, and locates the child nodes in a circular fashion around the root. Sub-trees formed by the branching of child nodes are located radially around the child nodes. This arrangement results in an ever-expanding concentric arrangement with radial proximity to the root node indicating the node level in the hierarchy.
