statechart

A state machine with nesting. Related states sit inside a larger box, and a trigger that applies to all of them is drawn once on the boundary of the group rather than repeated on every member. It can also say that leaving a group and coming back puts you where you were inside it. The cost is that it takes more reading, so reach for it once the repetition in a flat drawing has itself become the noise.

Example

Best when one trigger interrupts several states in the same way, or a cluster of states behaves as a unit.
