When I render this with LuaLaTex:
\documentclass[border=4mm]{standalone}\usepackage{tikz}\usetikzlibrary{graphdrawing,graphs} \usegdlibrary{layered,trees,circular,force}\begin{document}\tikz \graph [spring layout,edge quotes mid,edges={nodes={font=\scriptsize, fill=white, sloped, inner sep=1pt}}] {1 ->["Das"] 2 ->["ist"] 3 ->["das"] 4 ->["Haus"] 2 ->["vom" near start] 5 ->["Ni"] 4 ->["ko" near start] 1 ->["laus", orient=right] 5; };\end{document}I get this error:
Line 8: Package pgfkeys Error: I do not know the key '/tikz/"{Das}"' and I am going to ignore it. Perhaps you misspelled it.
Why?
