Mermaid to SVG
Drop in a Mermaid diagram (flowchart, sequence, gantt, class, ER, state, mindmap, etc.) or paste the code directly, and download a self-contained SVG. SVG scales infinitely without losing quality and embeds beautifully in HTML, docs, slides, and READMEs. Rendering runs locally in your browser — your diagram source never leaves your device.
