=======

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>

</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>

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.
