### Mermaid diagrams

Flowcharts, sequence diagrams, pie charts, and Gantt charts rendered as ASCII art. No external tools needed.
Flowcharts (every node shape, link style and direction, with subgraphs drawn as frames), state diagrams, class diagrams and ER diagrams are laid out as real box-and-arrow drawings that fit your terminal width; Gantt charts get a scaled time axis, mindmaps a tree, and sequence diagrams and pie charts a compact text form. Other diagram types show their source in a labelled box. Box-drawing characters by default, plain ASCII with `--ascii`. No external tools needed.
