Incremental Hierarchical Layout

This demo shows how to run the HierarchicalLayout algorithm on a predefined subset of nodes in a graph.

To achieve this, two setup steps are necessary:

The algorithm has to be told to work on a subset only. To do so, hierarchical layout's from sketch mode property has to be set to true.
The algorithm has to know which set of nodes (and edges) to rearrange. The class HierarchicalLayoutData offers the incrementalNodes
and incrementalEdges properties for this purpose.

In this demo, the algorithm is only applied to the orange nodes.

Things to Try

Click the button in the toolbar to run the incremental layout and observe the effect.
