title description
Mermaid Generation of diagram and flowchart from text in a similar manner as markdown

Mermaid is a library helping you to generate diagram and flowcharts from text, in a similar manner as Markdown.

Just insert your mermaid code in the mermaid shortcode and that's it.

Examples

Flowchart example

{{</*mermaid align="left"*/>}}
graph LR;
    A[Hard edge] -->|Link text| B(Round edge)
    B --> C{<strong>Decision</strong>}
    C -->|One| D[Result one]
    C -->|Two| E[Result two]
{{</* /mermaid */>}}

renders as

{{}} graph LR; A[Hard edge] -->|Link text| B(Round edge) B --> C{Decision} C -->|One| D[Result one] C -->|Two| E[Result two] {{}}

or you can use this alternative syntax:

```mermaid
graph LR;
    A[Hard edge] -->|Link text| B(Round edge)
    B --> C{Decision}
    C -->|One| D[Result one]
    C -->|Two| E[Result two]
```

renders as

graph LR;
    A[Hard edge] -->|Link text| B(Round edge)
    B --> C{Decision}
    C -->|One| D[Result one]
    C -->|Two| E[Result two]

Sequence example

{{</* mermaid */>}}
sequenceDiagram
    participant Alice
    participant Bob
    Alice->>John: Hello John, how are you?
    loop Healthcheck
        John->John: Fight against hypochondria
    end
    Note right of John: Rational thoughts <br/>prevail...
    John-->Alice: Great!
    John->Bob: How about you?
    Bob-->John: Jolly good!
{{</* /mermaid */>}}

renders as

{{}} sequenceDiagram participant Alice participant Bob Alice->>John: Hello John, how are you? loop Healthcheck John->John: Fight against hypochondria end Note right of John: Rational thoughts
prevail... John-->Alice: Great! John->Bob: How about you? Bob-->John: Jolly good! {{}}

Configuration

By default, mermaid is configured with default settings. You can customize mermaids default settings for all of your files thru a JSON object in your config.toml or override these settings sidewise thru your pages frontmatter.

This JSON object is forwarded into mermaids mermaid.initialize() function.

See mermaid documentation for all allowed settings.

Allow HTML in graphs

By default newer versions of mermaid disallow HTML in graphs if you are using default settings. To enable this, set the following line in your config.toml

[params]
  mermaidInitialize = "{ \"securityLevel\": \"loose\", \"startOnLoad\": true }"

or pages frontmatter
