Add an internal action or activity to a state in a statechart or activity diagram For information on UML diagrams in Visio 2013 and newer versions, see UML diagrams in Visio. Such a state diagram focuses on a set of attributes of a single abstraction (object, system).Note: The UML statechart diagram is not available in Visio 2013 and newer versions. It models the transitioning of states for an incident. Take a look at the State Machine Diagram below. A State Machine Diagrams shows the possible states of the object and the transitions that cause a change in state. The state of an object depends on its current activity or condition. ![]() The additional notations capture how activities are coordinated. In State Machines the vertices represent states of an object in a class and edges represent occurrences of events. Such an Activity Diagram focuses on the flow of data within a system. Take a look at the Activity Diagram which models the flow of actions for an incident. In particular, it is possible to represent concurrency and coordination in Activity Diagrams. Activity Diagrams capture high level activities aspects. In UML semantics, Activity Diagrams are reducible to State Machines with some additional notations that the vertices represent the carrying out of an activity and the edges represent the transition on the completion of one collection of activities to the commencement of a new collection of activities.
