tooltip

type: escString, default: ""

If tooltip is unset, Graphviz will use the object's label if defined.

Note that if the label is a record specification or an HTML-like label, the resulting tooltip may be unhelpful. In this case, if tooltips will be generated, the user should set a tooltip attribute explicitly.

digraph { label="Graph Label" tooltip="Graph Tooltip" subgraph cluster_a { label="Cluster Label" tooltip="Cluster Tooltip" Node1 [tooltip="Node1 Tooltip"] Node1 -> Node2 [label="Edge" tooltip="Edge Tooltip"] } }
