| <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. |
