我需要用latex构建下面的图表，有人能推荐一个包吗？

Question

我正在寻找在latex中构建以下图，但找不到如何准确生成它的示例，主要问题是通过“x”的路径。

  A
 / \
B   C
|\ /|
| x |
|/ \|
D   E

到目前为止，我已经尝试了'qtree‘和'linguistics{forest}’包。

对于简单的图形/图形，我使用tikz

\documentclass{scrartcl}

\usepackage{tikz}


\begin{document}
\begin{center}
    \begin{tikzpicture}[node distance=4cm]
        \node[draw=black,fill=white,circle,minimum size=1.5cm] (A) {A};
        \node[draw=black,fill=white,circle,minimum size=1.5cm, below left of = A] (B) {B};
        \node[draw=black,fill=white,circle,minimum size=1.5cm, below right of = A] (C) {C};
        \node[draw=black,fill=white,circle,minimum size=1.5cm, below of = B, yshift=-3cm] (D) {D};
        \node[draw=black,fill=white,circle,minimum size=1.5cm, below of = C, yshift=-3cm] (E) {E};

        \draw (A) -- (B);
        \draw (A) -- (C);
        \draw (B) -- (D);
        \draw (B) -- (E);
        \draw (C) -- (E);
        \draw (C) -- (D) node[draw=black,fill=white,circle,minimum size=1.5cm,midway] (X) {X};
    \end{tikzpicture}
\end{center}


\end{document}
