Is there a way to get static SVG (i.e. no JavaScript) out so you can incorporate the chart into a document, edit in Inkscape, etc., or does SVG+JavaScript inherently mean that the result is stranded in the browser?

Still, it's an interesting start.Correction: It somewhat works if you wrap the SVG in HTML:

although, when I load it into Inkscape the positioning of some text labels is way off (some aren't too bad) and some hidden elements are displayed.
