This is Pele, my new rendering library for diagrams and charts, compatible with the latest Mermaid syntax. - 100-500× faster than mermaid.js - 6× smaller bundle - No dependencies - Easy to theme - Responsive to device width - Open source (MIT) Try it at pele.run

Benchmark methodology missing: which diagram types, complexity, rendering target (SVG/Canvas), and Mermaid version? 100–500× is implausible without specifics.
