Mermaid is a JavaScript-based diagramming and charting tool that lets you create and maintain visualisations using Markdown-inspired syntax.
It’s aimed at keeping diagrams close to documentation and development workflows, so they’re easier to version, review, update, and embed across websites, documentation platforms, and supported applications.
This is free and open source software.
