Is there a way to set the location of the position of edge label when using the tikz graph package?
I attempted to look for samples of this being done in the manual, but was unable to find any (closest I got was in 19.6 where it shows how to set some options for individual edges).
Is this possible?
Edit: more specifically, I am looking for a way to put the label above or below the edge.
Edit to add MWE:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{graphdrawing,positioning,graphs}
\usegdlibrary{layered, trees}
\begin{document}
\begin{tikzpicture}
\begin{graph}
{1->[edge label=hello]2};
\end{graph}
\end{tikzpicture}
\end{document}

The labels seem to be placed with the
auto
option enabled, which places the node/label on the side of the line, in your MWE above it. As such you can add theswap
option to move the label to the other side.
