    <div id="placeholder" style="width:600px;height:300px;"></div>

    <p class="message"></p>

    <p>With the navigate plugin it is easy to add panning and zooming.
    Drag to pan, double click to zoom (or use the mouse scrollwheel).</p>

    <p>The plugin fires events (useful for synchronizing several
    plots) and adds a couple of public methods so you can easily build
    a little user interface around it, like the little buttons at the
    top right in the plot.</p>
