What UML diagrams have you worked with besides Sequence?

In addition to sequence diagrams (Sequence), I have worked with several other types of UML diagrams:

• Class diagrams — for modeling the structure of the system, describing classes, their attributes, and relationships.
• Use Case diagrams — for describing functional requirements and user interactions with the system.
• State diagrams — for modeling the behavior of objects depending on states.
• Activity diagrams — for describing business processes and workflows.

These diagrams help visualize different aspects of the system and facilitate communication between the team and the client.
