how to place tikzpicture from left edge of paper

Question

i'm using tikz to draw a diagram. But i meet the problem: latex place the tikzpicture with a distant to left edge of paper and its too large that goes over right edge. Like the picture below shows, theres still plenty of space at left corner, and right part of picture already gose out of page. I have done nothing than simply write:

\begin{figure}[!h]
    \centering
    \begin{tikzpicture}[square/.style={regular polygon,regular polygon sides=4}]
     %draw something large here
    \end{tikzpicture}
 \end{figure}

how can i place it correctly?

Answer 1

So i have solved it myself by using geometry package and combined it with resizebox:

\documentclass[12pt,ngerman,landscape]{article}
...
\usepackage{geometry}
\geometry{
         left=2mm,
         top=20mm,
         right=2mm,
}

\begin{document}
\begin{figure}[!h]
    \centering
    \resizebox{\linewidth}{!}{
    \begin{tikzpicture}[square/.style={regular polygon,regular polygon sides=4}]
         %% codes gose here
    \end{tikzpicture}}
\end{figure}
\end{document}

As the result, it uses the full space from left edge to right edge.
