 * Using QueryPath to Generate a Scalable Vector Graphic (SVG).

 * This file contains an example of how QueryPath can be used

 * XML format for creating graphics. You can find out more about it 
 * here: {@link http://www.w3.org/TR/SVG11/}.
 *
 * If you would like to view the SVG file that is created, the file is available
 * at {@link http://querypath.org/svg.php}. (That URL actually runs the script displayed
 * here.)
