Because many of the prospective authors voted for Inkscape in the course of this discussion, there shall be at least one example in Inkscape format.

Has anyone found an svg editor that works good on a Mac. I tried the MacPorts version of inkscape as recommended by the inkscape website and it won’t open a file so I’m not sure it works at all.
