Mermaid diagrams are supported in Congo using the mermaid shortcode. Simply wrap the diagram markup within the shortcode. Congo automatically themes Mermaid diagrams to match the configured colorScheme parameter.

Refer to the mermaid shortcode docs for more details.

The examples below are a small selection taken from the official Mermaid docs. You can also view the page source on GitHub to see the markup.
