Cluster

  A group of nodes is surrounded by a frame. In contrast to a box, edges from nodes outside the frame are drawn to nodes inside the frame and vice versa.

Here the layout is calculated as if the graph were unfolded, the only difference being that the nodes are placed according to the restrictions induced by the common frame. This often results in rather poor layout quality, layout calculation frequently being slow on account of the restrictions. Consequently, the boxed layout is preferable whenever possible.

Note: Clustering is an experimental feature. The layout of clustered subgraphs is quite challenging in nature. aiSee includes an experimental implementation of clustered layout which is not supported nor maintained. Nevertheless, many aiSee users find that feature quite useful.

Targets
The cluster operation can only be chosen for subgraphs (menu item Cluster Subgraph).  

Reverse Operation
A direct reverse operation is not implemented. To reverse a cluster operation, change the clustered subgraph into a box or fold it and then use Unfold/Unbox.
