Alternativ kann man mit der FFI von LuaTeX ≥ 1.0.3 oder LuaJITTeX und pplib das SVG direkt mit Cairo und RSVG2 rendern, siehe meine Antwort auf TeX.SX https://tex.stackexchange.com/a/408014
<code><pre>
lualatex --shell-escape test.tex
\# oder
luajittex --fmt=luajitlatex --shell-escape test.tex
</pre></code>
