`TikZ` (“TikZ ist kein Zeichenprogramm” — “TikZ is no drawing software”) is a powerful package for drawing vector graphics.
```{.lang-tex .hljs .small-text .scroll-one-half}
% …
\tikzstyle{every node}=[draw=black,thick,anchor=west]
\tikzstyle{selected}=[draw=red,fill=red!30]
\tikzstyle{dir}=[fill=gray!50]
\tikzstyle{relativeTo}=[fill=blue!70]
\begin{tikzpicture}[%
grow via
three points={one child at (0.5,-0.7) and
two children at
(0.5,-0.7) and (0.5,-1.4)},
edge from
parent path={(\tikzparentnode.south)
|- (\tikzchildnode.west)}]
\node {/ or C:}
child { node {home}
child { node {knut}
child { node {pictures}}
child { node {docs}
child { node [dir] {latex}
child { node [relativeTo] {main.tex}
child { node [selected] {part1.tex}
}
}
}
};
\end{tikzpicture}

Logical tableaux can be renderd using the `prftree` package.
```{.hljs .lang-tex .small-text .scroll-one-half}
\begin{displaymath}
\prftree[l,r]{}{[comp$\_{ns}$]}
{
\prftree[l,r]{}{[comp$\_{ns}$]}
{
\prftree[l,r]{}{[ass$\_{ns}$]}
{

}
{
(\texttt{m:=a}, \sigma\_{\bot,\bot})
\rightarrow \sigma\_{48,\bot}
}
}
{
\prftree[l,r]{}{[ass$\_{ns}$]}
{

}
{
(\texttt{n:=b}, \sigma\_{48,\bot})
\rightarrow \sigma\_{48,18}
}
}
{
(\texttt{m:=a; n:=b}, \sigma\_{\bot,\bot})
\rightarrow \sigma\_{48,18}
}
}
{
\prftree[l,r]{}{}
{
\dots
}
{
\textbf{[1]}\ (\texttt{LOOP}, \sigma\_{48,18})
\rightarrow \sigma\_{6,6}

{

\rightarrow \sigma\_{6,6}
