From the Visio Enterprise help : A State Machine, which is attached to a class or use case, is a graph of states and transitions that describes the response of an object to outside stimuli. A statechart diagram represents a State Machine. By documenting events and transitions, a statechart diagram shows the sequence of states an object goes through during its life. To represent a flow driven by internally generated actions rather than external events, use an Activity Diagram.
See, for example, Bug State Chart
