Features and limitations of the CL

Displays network topologies composed of interconnected rings or stars.

Provides three clustering modes (see Clustering mode (CL)). The first mode calculates the clusters automatically from the graph topology. The second mode requires a full specification of the clusters and the node orderings. The third mode assumes that the clusters are subgraphs whose initial position must be kept. The first and the third modes arrange the nodes of the cluster on circles by minimizing the link crossings, while the second mode keeps the specified node ordering. The first and the second mode place the clusters using a radial tree layout, while the third mode keeps the initial position of the clusters.

Takes into account the size of the nodes so that no overlapping occurs. (See also The CL algorithm).
