I have the following TikZ code:
\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows,automata}
\begin{document}
\begin{tikzpicture}[shorten >=1pt,node distance=2cm,>=stealth',thick]
\node[state] (1) {$1$};
\node[state,draw=none] (d1) [left of=1] {};
\draw [->] (1) to[loop above] node[auto] {} (1);
\draw [->] (1) to[bend left] node[auto] {} (d1);
\end{tikzpicture}
\end{document}
which produces this image:
Notice, that I've used a hidden node (d1) above in order to produce the nice arrow going to the left.
The sadness of this is that now I have a big circle-sized empty space.
I'd like to keep the arrow, I'd like the arrow to look the same, but I'd like to get rid of that empty space.
Is there a way to draw the arrow without introducing the invisible node? Or is there a way to crop the figure? What's an elegant way to solve this problem?
Thanks!
