TikZ/pgf is a portable graphics package developed for LaTeX, also supporting ConTeXt. It is a possible alternative to MetaPost & MetaFun.
TikZ is included as a (third party) module for ConTeXt.
Example
From the TikZ/pgf manual.
\setupcolors[state=start] \definecolor[darkgreen][g=.5] \usemodule[tikz] \starttext \starttikzpicture[ scale=3,line cap=round axes/.style=, important line/.style={very thick}, information text/.style={rounded corners,fill=red!10,inner sep=1ex} ] \draw[help lines,step=0.5cm] (-1.4,-1.4) grid (1.4,1.4); \draw (0,0) circle (1cm); \draw[->] (-1.5,0) -- (1.5,0) node[right] {$x$} coordinate(x axis); \draw[->] (0,-1.5) -- (0,1.5) node[above] {$y$} coordinate(y axis); \foreach \x/\xtext in {-1, -.5/-\frac{1}{2}, 1} \draw[xshift=\x cm] (0pt,1pt) -- (0pt,-1pt) node[below,fill=white] {$\xtext$}; \foreach \y/\ytext in {-1, -.5/-\frac{1}{2}, .5/\frac{1}{2}, 1} \draw[yshift=\y cm] (1pt,0pt) -- (-1pt,0pt) node[left,fill=white] {$\ytext$}; \filldraw[fill=green!20,draw=green!50!black] (0,0) -- (3mm,0pt) arc(0:30:3mm); \draw (15:2mm) node[green!50!black] {$\alpha$}; \draw[important line,red] (30:1cm) -- node[left=1pt,fill=white] {$\sin \alpha$} (30:1cm |- x axis); \draw[important line,blue] (30:1cm |- x axis) -- node[below=2pt,fill=white] {$\cos \alpha$} (0,0); \draw[important line,orange!80!black] (1,0) -- node[right=1pt,fill=white] { $\displaystyle \tan \alpha \black = \frac{{\red \sin \alpha}}{\blue \cos \alpha}$} (intersection of 0,0--30:1cm and 1,0--1,1) coordinate (t); \draw (0,0) -- (t); \draw[xshift=1.85cm] node[right,text width=6cm,information text] { The {\darkgreen angle $\alpha$} is $30^\circ$ in the example ($\pi/6$ in radians). The {\red sine of $\alpha$}, which is the height of the red line, is \startformula {\red \sin \alpha} = 1/2. \stopformula By the Theorem of Pythagoras ... }; \stoptikzpicture \stoptext
