    <p>
      This sample contains a draggable HTML element (using jQuery UI), which houses a GoJS Palette.
    </p>
    <p>
      A DIV to the right of the diagram houses the <a href="../extensions/DataInspector.html">GoJS Data inspector extension</a>,
      which displays some editable information about each Node.
