How is a flow final node represented in notation?

A flow final node is represented in notation as a circle with an X inside. This visual representation is designed to clearly distinguish it from other types of nodes in modeling diagrams. The flow final node indicates that flow is completed or that all flows leading into it have been concluded, effectively marking the end of the flow in the system.

This specific symbol helps modelers quickly identify the termination point in a process or sequence, which is crucial for understanding the flow of information or actions within the system being modeled. Recognizing this notation is essential for accurately interpreting and creating UML diagrams or any related models that include flow elements.

The other potential representations might depict different types of nodes or elements in modeling, but the circle with an X uniquely signifies the flow final node's purpose and function. Understanding this notation is a key aspect of effectively using modeling languages to communicate processes and behaviors within systems.
