One or more diagrams can be managed per Jira issue. The JQL field “mermaidCount” can be used to query issues by the number of diagrams.

The editor supports syntax highlighting and validation checks. Moreover, while editing the Mermaid code a live preview of the diagram is shown.

Mermaid diagrams can be opened in a (Jira) fullscreen dialog.

For best legibility, the diagram rendering bases on the users' current Jira theme.
