Easy to use
Easily create diagrams and charts with the Mermaid Live Editor.
A v13 proof of concept that is DOM-free and plugin-based, so you pick only the pieces you need. A flowchart-only bundle is about 100 kB (min+gzip) and renders about 50× faster than v12, aiming for 100×, with the same syntax.
Getting there means trade-offs between size and features, and between speed and layout quality. Should v13 be this rewrite, or gradual updates? Help us decide.
