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
<table>
    <tr><th>Code</th><th>Rendered diagram</th></tr>
    <tr>
        <td>
            <pre>
                <code>
graph TD;
    A-->B;
    A-->C;
    B-->D;
    C-->D;
                </code>
            </pre>
        </td>
        <td>
            <p align="center">
                <img src='http://www.sveido.com/mermaid/img/ex1.png' alt='Example 1'>
            </p>
        </td>
    </tr>
    <tr>
        <td>
            <pre>
                <code>
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 &lt;br/>prevail...
    John-->>Alice: Great!
    John->>Bob: How about you?
    Bob-->>John: Jolly good!
                </code>
            </pre>
        </td>
        <td>
            <img src='http://www.sveido.com/mermaid/img/seq1.png' alt='Example 2'>
        </td>
    </tr>
    <tr>
        <td>
            <pre>
                <code>
classDiagram
    Class01 <|-- AveryLongClass : Cool

    Class08 <--> C2: Cool label
                </code>
            </pre>
        </td>
        <td>
            <img src='./docs/img/class-diagram.png' alt='Example 3'>
        </td>
    </tr>
</table>

# Credits
Many thanks to the [d3](http://d3js.org/) and [dagre-d3](https://github.com/cpettitt/dagre-d3) projects for providing
the graphical layout and drawing libraries! Thanks also to the
[js-sequence-diagram](http://bramp.github.io/js-sequence-diagrams) project for usage of the grammar for the
sequence diagrams. Thanks to Jessica Peter for inspiration and starting point for gantt rendering.
