Use Case Diagram Examples in Lucidchart

Use case diagrams are surprisingly simple to create and understand. A use case diagram is meant to depict a high-level view of the relationship between systems, use cases, and actors. Keep in mind that use case diagrams shouldn't go into too much detail; for example, they won't explain the order in which steps are performed. Our UML-specific shapes are ideal for any UML diagram; with specialized connectors, you can model nearly any situation or system. Try it and see for yourself.
