Mermaid - Generation of diagram and flowchart from text in a similar manner as markdown

Mermaid is a Javascript based diagramming and charting tool that uses Markdown-inspired text definitions and a renderer to create and modify complex diagrams. The main purpose of Mermaid is to help documentation catch up with development. Diagramming and documentation costs precious developer time and gets outdated quickly. But not having diagrams or docs ruins productivity and hurts organizational learning.

Mermaid addresses this problem by cutting the time, effort and tooling that is required to create modifiable diagrams and charts, for smarter and more reusable content. The text definitions for Mermaid diagrams allows for it to be updated easily, it can also be made part of production scripts (and other pieces of code). So less time needs to be spent on documenting, as a separate and laborious task.

Mermaid was nominated and won the JS Open Source Awards (2019) in the category "The most exciting use of technology".
