\chapter{Graphics with PSTricks}
\noindent
\LaTeX\ has only limited drawing capabilities, while Post\-Script is a page
description language that has a rich set of drawing commands; there are programs
(such as \textsf{dvips}) that translate the \texttt{dvi} output to Post\-Script.
So, the natural question is whether one can include pure PostScript code in a
\TeX\ source file itself for programs such as \textsf{dvips} to process after
the \TeX\ compilation? This is the idea behind the \textsf{PSTricks} package of
Timothy Van Zandt. The beauty of it is that you don't need to know PostScript to
use it -- the necessary PostScript code can be generated by \TeX\ commands
defined in the package.
\section{Getting the points}
Any picture is drawn by stringing together appropriate points. How do we specify
the points we need? Thanks to the 17\textsuperscript{th}-century French
mathematicians Pierre de Fermat and Ren\'e Descartes, we have a method for
specifying each point in a plane using a pair of numbers. The method is to fix
a pair of perpendicular lines (called \emph{axes}) and label each point with
the numbers representing its distance from the nearest point on each axis (called
\emph{coordinates}).
