public class SimpleSVGGraphics2D
extends Graphics2D

Very simple SVGGraphics2D, only enough for basic rrd4j use, without dependencies. Plus a few things that rrd4j doesn't use, but not much. Unsupported things will throw UnsupportedOperationExceptions. Supports custom RenderingHints for id and class on top-level svg element. Supports custom RenderingHints for id, class, title, and arbitrary attributes on all drawn elements. Supports custom RenderingHints for inner SVG on all drawn elements except text. No standard Java AWT hints are supported. Antialiasing is done automatically. Antialiasing hints have no effect.
