Use Case Diagram Syntax
Use case diagrams visualize the functional requirements of a system by showing actors, use cases, and their relationships. SparkChart supports PlantUML syntax, making it easy to create professional use case diagrams from simple text.
Basic Examples
The simplest use case diagram consists of actors and use cases connected by relationships. Actors are represented as stick figures, and use cases are shown as ovals.
Actors and Use Cases
Actors represent users or external systems that interact with your system. Use cases represent the functionality or services provided by the system.
Relationships
Relationships connect actors to use cases and can represent associations, includes, extends, and generalizations.
Packages
Group related use cases together using packages or rectangles to organize your diagram.
