Tutorials, guides, and best practices for UML diagramming
Compare Mermaid and PlantUML class diagrams for relationships, namespaces, association classes, view trimming, and maintainable formal UML documentation.
OnUML uses Mermaid 11.6.0, where subgraph only approximates lanes. Compare it with 11.16.0 swimlane-beta and PlantUML activity swimlanes for role ownership.
Mermaid covers six common control fragments. PlantUML adds dedicated return, autoactivation, reference, and pagination syntax for complex interaction flows.
Choose Mermaid for everyday documentation and PlantUML for formal UML or complex architecture. Compare capabilities, version limits, and delivery scenarios.
Learn Mermaid flowchart syntax with practical examples for authentication, CI/CD, microservices, error handling, SSO, and e-commerce workflows.
Learn Mermaid sequence diagram syntax for participants, messages, notes, activation, control flow, and maintainable API documentation with runnable examples.
