uml

Quick Start: Choose diagram type → Write PlantUML text → Define elements and relationships → Wrap in ```plantuml fence. ⚠️ IMPORTANT: Always use ```plantuml or ```puml code fence. NEVER use ```text — it will NOT render as a diagram. draw-uml supports 9500+ mxgraph stencil icons (AWS, Azure, Cisco, Kubernetes, etc.) via the mxgraph.* syntax. Default colors are applied automatically — you do NOT need to specify fillColor or strokeColor . Full stencil reference: See stencils/README.md . - Every diagram starts with @startuml and ends with @enduml - Use standard PlantUML keywords: class , interface , abstract , enum , actor , participant , component , node , database , package - Relationships use arrow syntax: --> , , ..|> - Use skinparam for global styling and colors - Use #color on individual elements for specific colors - Notes use note left of , note right of , note over , or standalone note "text" as N - mxgraph. . — the stencil shape key (e.g. mxgraph.aws4.lambda , mxgraph.kubernetes.pod ) - "Label" — display text (quoted if contains spaces, unquoted for single word) - as — identifier for use in relationships - #color — optional override color (e.g. #FF6600 , #LightBlue )
