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.

Flowchart

graph TD;
    A-->B;
    A-->C;
    B-->D;

Sequence diagram

    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!

Sibling projects

Request for assistance

Things are piling up and I have hard time keeping up. To remedy this it would be great if we could form a core team of developers to cooperate with the future development mermaid.

As part of this team you would get write access to the repository and would represent the project when answering questions and issues.

Together we could continue the work with things like:

  • adding more typers of diagrams like mindmaps, ert digrams etc
  • improving existing diagrams

Don't hesitate to contact me if you want to get involved.
