The tree-dvips package is available at the usual places (follow this link for some suggestions. ]

The tree macros package allows one to integrate TeX and Postscript. For example, one can use TeX to layout a tree and have Postscript draw the lines.

These macros work by defining locations on a page and then manipulating them in a variety of ways. The commands that created the above tree are as follows:

\begin{tabular}{ccc}
                    &\node{a}{top node}\\[3ex]
\node{b}{left node} &     & \node{c}{right node}\\[3ex]
                    &     & \node{d}{odd node}
\end{tabular}
\nodeconnect{a}{b} 
\nodeconnect{a}{c}
\nodeconnect{c}{d}
\nodecurve[r]{a}[r]{d}{1in}
\anodeconnect[b]{b}[l]{d}
\anodecurve[l]{a}[l]{b}{1in}
