Diagrams (UML and SysML)

A diagram is a visual representation of a model that shows specific elements and their relationships to convey structure, behavior, or interactions within a system. In modeling tools, UML or SysML diagrams help engineers communicate design intent clearly and consistently. Each diagram type (class, activity, sequence) focuses on a different aspect of a system. They are essential for documentation, collaboration, validation, and aligning stakeholders around system architecture and design decisions.
