Diagrams | Hugo provides a sample sequence diagram example for markdown.
I have a similar sequence diagram captured in a markdown. The difference is that I have encapsulating box for participants. This causes an error in rendering the sequence diagram. To ensure syntactic correctness, I am able to render it in VSCode.
Sample code -
```mermaid sequenceDiagram box rgb(255, 244, 255) Setup participant ps as Server participant pc as Controller end box LightYellow Target participant ss as Setup Service end autonumber Note over ps,ss: Phase1 :: Procure Credentials pc->>ss: Test request ss->>pc: Response :: Test Response ```
vsCode renders well.
