Write a figure
The preamble of the latex file must contain:
\usepackage{tikz}
Some optional libraries could be add like this:
\usetikzlibrary{calc}
To start a figure, the code must be inside the tikzpicture environment like this:
\begin{tikzpicture} ... TikZ code here... \end{tikzpicture}
exemple
% Author: Quintin Jean-Noël
% <http://moais.imag.fr/membres/jean-noel.quintin/>
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary[topaths]
% A counter, since TikZ is not clever enough (yet) to handle
% arbitrary angle systems.
\newcount\mycount
\begin{document}
\begin{tikzpicture}[transform shape]
%the multiplication with floats is not possible. Thus I split the loop
%in two.
\foreach \number in {1,...,8}{
% Computer angle:
\mycount=\number
\advance\mycount by -1
\multiply\mycount by 45
\advance\mycount by 0
\node[draw,circle,inner sep=0.125cm] (N-\number) at (\the\mycount:5.4cm) {};
}
\foreach \number in {9,...,16}{
% Computer angle:
\mycount=\number
\advance\mycount by -1
\multiply\mycount by 45
\advance\mycount by 22.5
\node[draw,circle,inner sep=0.125cm] (N-\number) at (\the\mycount:5.4cm) {};
}
\foreach \number in {1,...,15}{
\mycount=\number
\advance\mycount by 1
\foreach \numbera in {\the\mycount,...,16}{
\path (N-\number) edge[->,bend right=3] (N-\numbera) edge[<-,bend
left=3] (N-\numbera);
}
}
\end{tikzpicture}
\end{document}
