Just to add,
I am noticing that the output of the generated 3DGauge isn't quite right if rendered client-side.
Here's what the image looks like if rendered as either a base-64 encoded image or as a native SVG in Firefox or Chrome (as IE8 or lower does not natively support either)...

So it appears that something isn't right in either the SVG, SVA, or the rendering engine itself.
Hope this info helps!
