<p>The <code>mermaid</code> shortcode generates diagrams and flowcharts from text, in a similar manner as Markdown using the <a href="https://mermaidjs.github.io/" target="_blank">Mermaid</a> library.</p>

<p>This only works in modern browsers.</p>
</div>
</div>
<h2 id="usage">Usage</h2>
<p>While the examples are using shortcodes with named parameter it is recommended to use codefences instead. This is because more and more other software supports Mermaid codefences (eg. GitHub) and so your markdown becomes more portable.</p>
<p>You are free to also call this shortcode from your own partials.</p>

<h2 id="configuration">Configuration</h2>
<p>Mermaid is configured with default settings. You can customize Mermaid’s default settings for all of your files thru a JSON object in your <code>hugo.toml</code>, override these settings per page thru your pages frontmatter or override these setting per diagramm thru <a href="https://mermaid-js.github.io/mermaid/#/directives?id=directives" target="_blank">diagram directives</a>.</p>
<p>The JSON object of your <code>hugo.toml</code> / frontmatter is forwarded into Mermaid’s <code>mermaid.initialize()</code> function.</p>
<p>See <a href="https://mermaid-js.github.io/mermaid/#/Setup?id=mermaidapi-configuration-defaults" target="_blank">Mermaid documentation</a> for all allowed settings.</p>
<p>The <code>theme</code> setting can also be set by your used color variant. This will be the sitewide default and can - again - be overridden by your settings in <code>hugo.toml</code>, frontmatter or diagram directives.</p>
