Mermaid.js

Overview

Mermaid.js is a JavaScript-based text-to-diagram tool that renders diagrams from Markdown-like syntax. It is the de facto standard for embedding diagrams in Markdown because GitHub, GitLab, Azure DevOps, Notion, Docusaurus, and many other platforms render Mermaid code blocks natively. You write text; the platform renders a diagram.
