Change colour & line width of an Annotation in JFreeChart

Question

I am adding an annotation to my plot, but I can't work out how to change the colour or line width (stroke) of this. I've read through the documentation as best as I can but I'm out of ideas. Can anyone help?

Shape shape = new Ellipse2D.Double(circleXValue - radius, circleYValue - radius, radius + radius, radius + radius);
XYShapeAnnotation annotation = new XYShapeAnnotation(shape);
// ??
plot.addAnnotation(annotation);

You're using this constructor:

public XYShapeAnnotation(java.awt.Shape shape)

You may want to use one of these constructors that specify additional parameters:

public XYShapeAnnotation(
    java.awt.Shape shape,
    java.awt.Stroke stroke,
    java.awt.Paint outlinePaint)

public XYShapeAnnotation(
    java.awt.Shape shape,
    java.awt.Stroke stroke,
    java.awt.Paint outlinePaint,
    java.awt.Paint fillPaint)
