You can get my style file by anonymous ftp 
in sun.soe.clarkson.edu:pub/tex/latex-style/nodeedge.shar.

It draws direct slanted lines using epic/eepic commands by default, 
but I think you can draw such a tree 
with an additional macro definition for \crank as below.

Ex.
\documentstyle[epic,ecltree]{article}

\makeatletter
\newdimen\@midY
\def\crank#1(#2,#3)(#4,#5){%
        \@midY=#3\p@\advance\@midY by #5\p@\divide\@midY by 2\relax
        \edef\@MidY{\expandafter\@RemoveDim\the\@midY}%
        #1(#2,#3)(#2,\@MidY)(#4,\@MidY)(#4,#5)}
\makeatother

\begin{document}

\drawwith{\crank\drawline}

\begin{bundle}{A}
\chunk{\begin{bundle}{B}
        \chunk{C}
        \chunk{D}
        \chunk{E}
        \chunk{I}
        \end{bundle}}
\chunk{J}
\chunk{K}
\end{bundle}

\end{document}
