我非常接近能够生成一个看起来并不糟糕的家谱，但我遇到了以下问题。

//file: tree.dot
digraph {
    edge [dir=none];
    node [
        fillcolor="black",fixedsize=true,shape=box,
        style="rounded,filled",width=2.0
    ];
    splines=ortho;
    // GEN -01
    {
        rank=same; rankdir=LR;
        "Grandfather" [regular=0];
        m0002 [
            label="",shape=diamond,regular=0,height=0.25,
            width=0.25,style="filled",
        ];
        "Grandmother" [regular=0];
        {
            rank=same; rankdir=LR;
            "Grandfather" -> m0002 -> "Grandmother";
        }
    }
    m0002 -> c0001;
    // GEN  00
    {
        rank=same; rankdir=LR;
        c0000 [
            label="",shape=circle, regular=0, height=0.05,
            width=0.05,style="filled"
