Are you familiar with the elements of UML Use Case diagrams?

Yes, I am familiar with the elements of UML Use Case diagrams. The main elements include:

• Actors — external participants interacting with the system (users, other systems).
• Use Cases — functions or actions that the system performs upon request from actors.
• Associations — lines showing interactions between actors and use cases.
• System Boundary — a frame that limits the scope of the system, within which the use cases are contained.

Use Case diagrams help visualize system requirements from the perspective of users and their interactions with the functionality.
