Network Topology Diagram Generator

Quick Start: Choose topology type → Declare stencil icons for network devices → Connect with arrow syntax → Group into zones with rectangle or package → Wrap in ```plantuml fence.

⚠️ IMPORTANT: Always use ```plantuml or ```puml code fence. NEVER use ```text — it will NOT render as a diagram.

Critical Rules

• Every diagram starts with @startuml and ends with @enduml
• Use mxgraph.* stencil syntax for network device icons (routers, switches, firewalls, etc.)
• Default colors are applied automatically — you do NOT need to specify fillColor or strokeColor
• Use rectangle "Zone" { ... } or package "Zone" { ... } to group devices into network zones
• Use cloud "Name" { ... } for cloud/Internet shapes
• Bidirectional physical links use -- (no arrow); directed flows use -->
• Dashed lines for VPN/wireless/logical links use .. or ..>
• Use skinparam for global styling
