clusterrank

type: clusterMode, default: local

Mode used for handling clusters. If clusterrank=local, a subgraph whose name begins with cluster is given special treatment.

The subgraph is laid out separately, and then integrated as a unit into its parent graph, with a bounding rectangle drawn about it. If the cluster has a label parameter, this label is displayed within the rectangle.

Note also that there can be clusters within clusters.

The modes clusterrank=global and clusterrank=none appear to be identical, both turning off the special cluster processing.
