Generation of diagrams and flowcharts from text in a similar manner as markdown.

Ever wanted to simplify documentation and avoid heavy tools like Visio when explaining your code?

This is why mermaid was born, a simple markdown-like script language for generating charts from text via javascript.

The code below would render the following image

Code	Rendered diagram
graph TD; A-->B; A-->C; B-->D; C-->D;
sequenceDiagram participant Alice participant Bob Alice->>John: Hello John, how are you? loop Healthcheck John->>John: Fight against hypochondria end Note right of John: Rational thoughts <br/>prevail... John-->>Alice: Great! John->>Bob: How about you? Bob-->>John: Jolly good!

Many thanks to the d3 and dagre-d3 projects for providing the graphical layout and drawing libraries! Thanks also to the js-sequence-diagram project for usage of the grammar for the sequence diagrams. Thanks to Jessica Peter for inspiration and starting point for gantt rendering.

Mermaid was created by Knut Sveidqvist for easier documentation.

Knut has not done all work by him self, here is the full list of the projects contributors.
