hi,
:)
it's easy to make this example with tikz.
\documentclass[]{article}
\usepackage{tikz,fullpage}
\begin{document}
\begin{tikzpicture}
\node[draw](A) at (0,0) {A};
\node[draw](B) at (2,3) {B};
\node[draw](C) at (5,0) {C};
\node[draw](D) at (6,1) {D};
\node[draw](E) at (6,4) {E};
\draw (B.south)--(C.north);
\draw (B.south)--(A.north);
\begin{scope}
\clip (B.south)--(C.north)--(A.north)--cycle;
\draw[fill=black](B.south) circle(0.5cm);
\end{scope}
\draw (B.east)--(D.west);
\draw (B.east)--(E.west);
\begin{scope}
\clip (B.east)--(D.west)--(E.west)--cycle;
\draw[](B.east) circle(0.5cm);
\end{scope}
\end{tikzpicture}
\end{document}
