Your viewBox certainly doesn't intersect any of the coords
in your example source code. When you add the elements to the
Document you need to place your circles in the 'maps' coordinate
system (which normally is simplier for you).
So the cx & cy for a circle should look something like
cx="425100"
cy="-519100"
