instances and returns a Number.
This class supports both minimum-link clustering, in which the distance between clusters is measured as the distance between the two nearest items in each cluster, and maximum-link clustering, in which distance is measured using the two furthest items in each cluster.
For a richer description, see the Wikipedia article on Cluster Analysis.

Parametersgroup:String |
| calculate | () | method |
public function calculate(list:DataList, d:Function):voidCalculates the community structure clustering. As a result of this method, a cluster tree will be computed and graph nodes will be annotated with both community and sequence indices.
Parameterslist:DataList — a data list to cluster

|
d:Function — a distance function

| operate | () | method |
public override function operate(t:Transitioner = null):voidPerforms an operation over the contents of a visualization.
