### Remarks

Unity calls this method when the graph is disabled, or is destroyed. Override this method to release resources, clear temporary data, or perform any required cleanup. This method complements [Graph.OnEnable](/engine/6000.6/script-reference/unity/graphtoolkit/editor/graph/onenable.md) and is useful for maintaining consistency across editor sessions.
