Hi Yasmin,
Your test code worked fine for me with one change, you had:
Element e =
doc.createElementNS(SVGNS,"spot");
This isn't right you want:
Element e =
doc.createElementNS(SVGNS,"circle");
Which is odd because an earlier e-mail had 'circle'
I tested by opening 'samples/mapSpain.svg'. I think two of your circles
still didn't show because mapSpain isn't quite large enough but the ones
that should show did.
