A use case diagram is a graphical depiction of a user's possible interactions with a system. A use case diagram shows various use cases and different types of users the system has and will often be accompanied by other types of diagrams as well. The use cases are represented by either circles or ellipses. The actors are often shown as stick figures.
UML diagrams such as activity diagrams, sequence diagrams, communication diagrams, and state machine diagrams can also be used to visualize usecases accordingly...
