TikZ 中的简化家谱

Question

我正在尝试使用 TikZ 制作如下所示的简化家谱。

我知道家谱树包装和我怎样才能改进 TikZ 中的这棵家谱？，但这些树太复杂了，因为它们有名字并使用颜色。我正在寻找更简单的东西，比如上面的那个。

我怎样才能做到这一点？

Answer 1

我不知道你想如何使用它，但你总是可以用 Ti 定义一些样式钾然后您可以使用 Z 来创建不同的家谱。

这可能会帮助你入门（也许不是最优雅的方式）：

\documentclass[border=10pt]{standalone}
\usepackage{tikz}
\usetikzlibrary{calc, shapes}

\tikzset{
    family tree/.style={
        every node/.style={
            inner sep=0pt
        },
        person/.style={
            minimum size=15pt,
            circle
        },
        woman/.style={
            person,
            draw
        },
        man/.style={
            person,
            label={[%

        },
        marriage/.style={
            double, 
            double distance=2pt,

    }
}
