[pstricks] Drawing graphs

[Francisco A. S. Grossi]

You can use pstree just you ould define a tree (a tree is compose of two 
subtrees) and not be concerned AT ALL with node position. PSTRICKS does it 
for you.

\usepackage{pst-tree}

\begin{document}
\begin{figure}[H]\centering
 \psset{linecolor=blue,levelsep=1.2,treesep=1}
 \pstree{\Tcircle{\red A}}{
    \pstree{\Tcircle{\red B}}{
       \pstree{\Tcircle{\red C}}{
          \Tcircle{\red D}
          \Tcircle{\red E}
       }
       \pstree{\Tcircle{\red F}}{
          \Tcircle{\red G}
       }
       \Tcircle{\red H}
    }
    \pstree{\Tcircle{\red I}}{
       \pstree{\Tcircle{\red J}}{
          \Tcircle{\red K}
          \Tcircle{\red L}
       }
       \Tcircle{\red M}
       \Tcircle{\red N}
    }
    \pstree{\Tcircle{\red O}}{
       \pstree{\Tcircle{\red P}}{
          \Tcircle{\red Q}
          \Tcircle{\red R}
          \Tcircle{\red S}
          \Tcircle{\red T}
       }
       \Tcircle{\red U}
       \Tcircle{\red V}
    }
 }
\end{figure}
