beautiful-mermaid is a library that renders diagrams written in Mermaid syntax as good-looking SVGs or ASCII art. It provides themes that refine the output style of the default Mermaid renderer, and for places that cannot display graphics, such as terminals or code comments, it also generates an ASCII version that draws the same diagram with text characters. It is used to improve the quality of flowcharts, sequence diagrams, and the like in documentation and READMEs.
