# [texhax] Drawing graphs with TikZ

Recently I have been trying to make figures of directed graphs (nodes
and arrows between them) , and all my efforts have failed.  I simply
do not understand what is going on.  As a final attempt, I have tried
to reproduce the figure on page 36 of the Tikz and pgf manual (version
1.18), where the latex file has been reduced to the bare essentials
like this:

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\path ( 0:2) node [shape=circle,draw] {}
( 0:1) node [shape=circle,draw] {}
( 0:0) node [shape=circle,draw] {}
( 1,1) node [shape=rectangle,draw] {}
(-1,1) node [shape=rectangle,draw] {};

\end{tikzpicture}
\end{document}

This results in a figure nothing like the one in the manual, where the
circles are all along a horizontal line (rather than vertical) with
the squares above and somewhat to the left of the sequence of the
circles.  As far As I am able to see, this is an exact reproduction of
the example.

Can anyone point at my error?
