Yes, I assume you will want to do this from Java, so make sure
to tell the canvas to be dynamic:
http://xmlgraphics.apache.org/batik/faq.html#display-does-not-update
The you can adjust the stroke-width with something as simple as:
SVGDocument doc = canvas.getSVGDocument(); // canvas is your
JSVGCanvas
SVGSVGElement root = doc.getRootElement();
root.setAttributeNS(null, "stroke-width", "10");
In this case the change in stroke width will cascade down the
rendering tree (for your very simple SVG document this might work
for you).
If you needed/wanted to only adjust the line elements
you might use DOM calls like getElementsByTagNameNS, or iterate
through all the children of the root with getFirstChild() and
getNextSibling() methods.
