I tried that and it was even stranger.
My code is essentially:
// Create an instance of org.w3c.dom.Document
Document document = impl.createDocument(svgNS, "svg", null);
Rectangle2D b2d = new Rectangle2D.Double(0, 0, 600, 400);
// Create an instance of the SVG Generator
SVGGraphics2D svgGenerator = new SVGGraphics2D(document);
svgGenerator.setSVGCanvasSize(new Dimension((int) b2d.getWidth(),
(int) b2d.getHeight()));
//This generates the graph
graph.draw(svgGenerator, b2d);
//*** This viewBox attribute causes corruption
Element el = svgGenerator.getRoot();
el.setAttributeNS(svgNS, "viewBox", "0, 0, 600, 400" );
If I comment out the two lines after *** I get (as expected):

If I include the two lines after *** I get the entire file as attached
below.
Note complete absence of viewBox and any other data! The draw method is not
threaded in any way. Any ideas?
