Mermaid makes drawing flowcharts and sequence diagrams really easy, but the default rendering is far from beautiful, let alone usable in the terminal. I found a new open-source project on GitHub: beautiful-mermaid, which is specifically designed to make Mermaid rendering both beautiful and practical — it can export exquisite SVGs or generate terminal-friendly ASCII art. It's implemented in pure TypeScript with no DOM dependencies, and covers five commonly used diagram types in one go: flowcharts, state diagrams, sequence diagrams, class diagrams, and ER diagrams. GitHub: https://github.com/lukilabs/beautiful-mermaid… Theme support is also on point: 15 carefully selected built-in themes, with details like accent colors and border colors fully customizable, and it even supports directly applying any VS Code theme color scheme. More importantly, all colors are driven by CSS variables: switching themes doesn't require re-rendering – just change the variables and it takes effect instantly.
