I use tikz to draw a three nodes in a triangle, connected by arrows. I want to add a rounded edge from each node to itself, basically adding edges like
\path[<->] (left) edge (left)
to the example below. However, it seems that it does not seem to work like this. Can anyone give me a hint on how to approach this/where to look?
\begin{tikzpicture}
\draw(0,0)node[left] (left){news media };
\draw(5,0)node[right] (right) {citizens};
\draw(60:5)node[above] (above){political actors};
\path[<->] (left) edge (right);
\path[<->] (left) edge (above);
\path[<->] (above) edge (right);
\end{tikzpicture}
loop left
, described in section 70.4 in the pgfmanual on page 748?
