Flowchart

Draft with Rovo, render live — ask for a diagram in plain English, paste it into the macro, done.

More details

Diagrams-as-code for Confluence: type /Mermaid, paste your diagram source, and it renders inline as an interactive SVG. Flowcharts, sequence/class/state (UML), ERD, Gantt, pie, git graphs, mindmaps, and more.

PDF page exports include your rendered diagrams — clean, no UI controls
Word exports include your diagram source as a readable code block
Renders inside Expand sections; errors show the reason, never a blank gap
SVG/PNG export, zoom, light/dark themes

Works with Rovo: ask Rovo to draft a diagram in Mermaid syntax, paste it into the macro, and it renders live.

Privacy: runs on Atlassian Forge with zero data access permissions (scopes: []), no external calls, no tracking. Your diagram source never leaves Confluence. SOC 2 Type II and GDPR inherited from Forge.

Companion to Mermaid Diagrams for Jira — same engine, same-day updates.
