How to use SVG for custom node shapes in graphviz?

Question

I\'m trying to use graphviz (the dot command-line tool, to be more specific) to generate a SVG layout of a graph. I would like to use my Inkscape-generated SVG file

Answer 1

graphviz only supports SVG input where the width and height attributes are set on <svg> using absolute units (pixels, inches etc.). Inkscape outputs height="100%" width="100%" viewBox="0 0 width_in_pixels height_in_pixels" as attributes on the <svg> element.

I filed a bug report, and a graphviz developer pointed me to the help for the image attribute, which describes the requirements for using SVG in custom node shapes.
