Bring existing diagrams

Flowcharts (graph/flowchart), sequence diagrams and state diagrams use the widely adopted text syntax, including diagrams written for Mermaid, so existing diagrams render unchanged. Set vhyxchart.renderCompatibleFences in VS Code, or pass { compatibleFences: true } to autoRender, to also render those existing code fences.

What stays the same

• All node shapes, edge kinds (--> -.-> ==> --- --o --x <--> ~~~), labels, &, subgraph, classDef, class, :::, style.
• Sequence arrows, activations, notes, loop/alt/else/opt/par/and/critical/break/rect, autonumber.
• stateDiagram-v2 with [*].
