In fact no , because in this function :
chartBean.getChart().draw(svgGenerator, new Rectangle2D.Double(0, 0,
chartBean.getWidth(), chartBean.getHeight()), null);
The chart is transform to a classic Graphics2D
and it's in the .stream() function that the Graphics2d is transform to
litteral SVG, am I right?
