 <h2 id="Overview">Overview</h2>
 <p>
    The Timeline is an interactive visualization chart to visualize data in time.
    The data items can take place on a single date, or have a start and end date (a range).
    You can freely move and zoom in the timeline by dragging and scrolling in the
    Timeline. Items can be created, edited, and deleted in the timeline.
    The time scale on the axis is adjusted automatically, and supports scales ranging
    from milliseconds to years.
 </p>
 <h2 id="Example">Example</h2>
 <p>
    The following code shows how to create a Timeline and provide it with data.
    More examples can be found in the <a href="../examples">examples</a> directory.
 </p>

 &lt;/script&gt;
 &lt;/body&gt;
 &lt;/html&gt;
 </pre>
 <h2 id="Loading">Loading</h2>
 <p>
    Install or download the <a href="http://visjs.org" target="_blank">vis.js</a> library.
    in a subfolder of your project. Include the library script in the head of your html code:
 </p>
 <pre class="prettyprint lang-html">
 &lt;script type="text/javascript" src="vis/vis.js"&gt;&lt;/script&gt;
 </pre>
 The constructor of the Timeline is <code>vis.Timeline</code>
 <pre class="prettyprint lang-js">var timeline = new vis.Timeline(container, items, options);</pre>
 The constructor accepts three parameters:
 <ul>
    <li>
        <code>container</code> is the DOM element in which to create the graph.
    </li>
    <li>
        <code>items</code> is an Array containing items. The properties of an
        item are described in section <a href="#Data_Format">Data Format</a>.
    </li>
    <li>
        <code>options</code> is an optional Object containing a name-value map
        with options. Options can also be set using the method
        <code>setOptions</code>.
    </li>
 </ul>
 <h2 id="Data_Format">Data Format</h2>
 <p>
    The Timeline uses regular Arrays and Objects as data format.
    Data items can contain the properties <code>start</code>,
    <code>end</code> (optional), <code>content</code>,
    <code>group</code> (optional), and <code>className</code> (optional).
 </p>
 <p>
    A table is constructed as:
 </p>
 <pre class="prettyprint lang-js">
 var items = [
    {
        start: new Date(2010, 7, 15),
        end: new Date(2010, 8, 2),  // end is optional
        content: 'Trajectory A'
        // Optional: a field 'group'
        // Optional: a field 'className'
        // Optional: a field 'editable'
    }
    // more items...
 ]);
 </pre>
 <h3>Properties</h3>
 <p>
    The item properties are defined as:
 </p>
 <table>
    <tr>
        <th>Name</th>
        <th>Type</th>
        <th>Required</th>

    <tr>
        <td>content</td>
        <td>String</td>

            all items with the same group are placed on one line.
            A vertical axis is displayed showing the groups.

            people, rooms, or other resources next to each other.<br>
        </td>
    </tr>
    <tr>
        <td>className</td>
        <td>String</td>
        <td>no</td>
        <td>This field is optional. A className can be used to give items
            and individual css style. For example, when an item has className
            'red', one can define a css style
            <code>
                .red {
                background-color: red;
                border-color: dark-red;

 <p>For example, to change the border and background color of all items, include the
    following code inside the head of your html code or in a separate stylesheet.</p>
 <pre class="prettyprint lang-html">&lt;style&gt;

 /*
 This is a graphviz-produced layout of the "family tree" of a fraternity and sorority.
 Each member in the graph was assigned a "big brother" from one organization and a "big sister" from the other. Blue icons represent Brothers from the fraternity, Pink represents Sisters from the sorority (Purple members are in both organizations - like honoraries.)
 Charter members (who can have no parent nodes) are outlined.

 We're experimenting with different ways of coloring and graphing, but found this the easiest for now. When we have more people in, we might look at different shades depending on generation number -- earlier people would get lighter colors, more recent members darker. Thumbnail images would be an interesting alteration as well.

 ##"I played some days with making an interface between our ConceptBase system (essentially a database system to store models) and graphviz. One example graph is attached. It is a so-called petri net for Dutch traffic lights. The example is actually taken from a book by Wil van der Aalst." Contributed by Manfred Jeusfeld.
