+++ description = "Generation of diagram and flowchart from text in a similar manner as markdown" title = "Mermaid" +++
Mermaid is a library helping you to generate diagram and flowcharts from text, in a similar manner as Markdown.
Usage
Just insert your mermaid code in the mermaid
shortcode like this:
{{</* mermaid [ align=(left|right|center|justify) ] */>}}
classDiagram
Person *-- Dog
{{</* /mermaid */>}}
You can set an optional align
attribute which defaults to center
.
If you don't need alignment you can use the alternative syntax using code fences:
```mermaid
classDiagram
Person *-- Dog
```
The generated graphs can be be panned by dragging them and zoomed by using the mousewheel. On mobile devices you can use finger gestures.
Examples
Flowchart
{{< mermaid align="left" >}} graph LR; A[Hard edge] -->|Link text| B(Round edge) B --> C{Decision} C -->|One| D[Result one] C -->|Two| E[Result two] {{< /mermaid >}}
{{% expand "Show markup" "true" %}}
{{</* 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 */>}}

Configuration
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.
Example
[params]
mermaidInitialize = "{ \"theme\": \"dark\" }"
or pages frontmatter
+++
mermaidInitialize = "{ \"theme\": \"dark\" }"
