I tried this (because of the suggestion):
Element e = Document.get().createElement("svg");
e.setAttribute ("width","400");
e.setAttribute ("height","400");
e.setAttribute ("xmlns","http://www.w3.org/2000/svg";);
e.setAttribute ("version","1.1");
setElement(e);
But the svg element wasn't recognized by Snap.
or use a <div> for your widget and let Snap create the SVG element (and

This is what I would prefer:
private native void testLib (Element container)
/*-{
var s = $wnd.Snap (400,400);
var c = s.circle (150,150,100);
container.appendChild (s);
}-*/;
But this leads to:
"An attempt was made to reference a Node in a context where
it does not exist."
