cluster
Whether the subgraph is a cluster
type: bool, default: false
Subgraph clusters are rendered differently, e.g. dot renders a box around subgraph clusters, but doesn't draw a box around non-subgraph clusters.
Example:
digraph cats {
subgraph cluster_big_cats {
// This subgraph is a cluster, because the name begins with "cluster"
"Lion";
"Snow Leopard";
}
subgraph domestic_cats {
// This subgraph is also a cluster, because cluster=true.
cluster=true;
"Siamese";
"Persian";
}
subgraph not_a_cluster {
// This subgraph is not a cluster, because it doesn't start with "cluster",
// nor sets cluster=true.
"Wildcat";
}
