Business Process & Integration Diagram Generator
Quick Start: Choose diagram type → Declare stencil icons for events/gateways/tasks → Group into pools/lanes → Connect with arrow syntax → Wrap in ```plantuml fence.
⚠️ IMPORTANT: Always use
```plantumlor```pumlcode fence. NEVER use```text— it will NOT render as a diagram.
Critical Rules
- Every diagram starts with
@startumland ends with@enduml - Use
left to right directionfor process flows (start→end reads left-to-right) - Use
mxgraph.bpmn.*for BPMN events, gateways, and task markers - Use
mxgraph.eip.*for Enterprise Integration Pattern icons - Use
mxgraph.lean_mapping.*for Value Stream Mapping symbols - Default colors are applied automatically — you do NOT need to specify
fillColororstrokeColor - Use
rectangle "Pool" { ... }for BPMN pools and lanes - Sequence flows use
-->, message flows use..>(dashed)
Full stencil reference: See stencils/README.md for 9500+ available icons.

Quick Example
@startuml
left to right direction
mxgraph.bpmn.event.start "Start" as start
rectangle "Review\nRequest" as review
mxgraph.bpmn.gateway2.exclusive "Approved?" as gw
rectangle "Process\nOrder" as process
rectangle "Notify\nRejection" as reject
mxgraph.bpmn.event.end "End" as end_ok
mxgraph.bpmn.event.end "End" as end_fail
start --> review
review --> gw
gw --> process : "Yes"
gw --> reject : "No"
process --> end_ok
reject --> end_fail
