<p>
The applet (<a href="demo/AppletDemo.java">view source</a>) displays
the
<a href="http://svn.apache.org/repos/asf/xmlgraphics/batik/trunk/samples/barChart.svg">barChart.svg</a>
sample from the Batik distribution using a <code>JSVGCanvas</code>.
Script in the web page then interacts with the applet, by calling the
<code>updateBar</code> method of the applet object when the
<b>Update chart</b> button is pressed. This method modifies the
SVG document being displayed to update the heights of the bars.
