Clusters

A cluster is a group of nodes forming a sub-graph.

Clusters are visualized with a blue rectangle. Clusters can be folded and unfolded using the context menu on the cluster.

Folded clusters will contain a single “dummy” node which allows you to continue working with the folded cluster as with any other node, e.g.: apply filtering.

Cluster Editor

You can use the Cluster Editor to manage clusters.

• Use the filter on the left side to select nodes outside clusters and the “Add” button to add those to the selected cluster
• Use the context menu on the right side to delete and merge clusters
• Use CTRL+RMB to open the context menu without selecting a node automatically to allow creation of new clusters.
• Use Drag & Drop on the right side to move nodes and clusters into clusters

Manage clusters within the graph

You can use the context menu on a node to add (selected) nodes(s) to a cluster from within the graph.

Clusters in DOT language

In order to create clusters in a DOT file add the respective nodes to a “subgraph” and prefix the subgraph with “cluster_”.

digraph {
  subgraph "cluster_C1" {
    label = "Feature A"

    Builder
    Component
    Factory
    IComponent 
    POCO1
    POCO2
  }

  ...
}
