About Beauty Diagram
Most diagrams shipped in READMEs, docs, and decks look the same: stiff Mermaid defaults, boxy PlantUML, or hand-drawn draw.io exports that never quite match the rest of the slide. Beauty Diagram fixes that without forcing you to redraw anything. Paste a Mermaid, PlantUML, draw.io source, pick a theme, and get a clean SVG or PNG you can drop straight into a deck, blog post, Notion page, or product spec. The same source can render as a public share link or as an <img src> embed URL — so your README diagrams stay live and updateable instead of going stale. It works wherever you write code…
