JFreeChart to SVG, No XML Tag, Store Into String

I would like to generate the SVG without these tags showing up:
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE svg PUBLIC '-//W3C//DTD SVG 1.0//EN'
'http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd'>

I would also like to store the SVG code into a string or string buffer
variable. Here is my current code:

public class export2svg {
	
	public static void main(String[] args) throws SVGGraphics2DIOException,
UnsupportedEncodingException {
		DefaultPieDataset dataset = new DefaultPieDataset();
		dataset.setValue("1", 43.2);
		dataset.setValue("2", 27.9);
		dataset.setValue("3", 70.5);
		
		JFreeChart chart = ChartFactory.createPieChart(
				"Sample Pie Chart",
				dataset,
				true,
				true,
				false);
		
		DOMImplementation domImpl =
GenericDOMImplementation.getDOMImplementation();
		
		Document document = domImpl.createDocument(null, "svg", null);
		
		SVGGraphics2D svgGenerator = new SVGGraphics2D(document);
		
		svgGenerator.getGeneratorContext().setPrecision(6);
		svgGenerator.setSVGCanvasSize(new Dimension(200, 200));
		
		chart.draw(svgGenerator, new Rectangle2D.Double(0, 0, 200, 200), null);
	
		boolean useCSS = true;
		Writer out = new OutputStreamWriter(System.out, "UTF-8");

		svgGenerator.stream(out, useCSS);
			
	}
}

I appreciate any advice. Thank you!

   This can be accomplished by 'calling 'getRoot()' on the
SVGGraphics2D to get the root of the generated SVG Tree.

The pass that Element to 
        batik.dom.util.DOMUtilities.writeNode(Node n, Writer w);

   Use a java.io.StringWriter for the second argument.
