集合论/维恩图图表绘制

Question

我正在尝试重现如下图表：

但我唯一的工具是数学而且必须手动完成，虽然您可以检查 tikz 代码，但不太准确，因为您必须覆盖最厚的部分，如图所示，而且它永远不会匹配。我必须画半圆来突出显示区域和子集。有没有其他更准确和快速的工具/方法？还提供 MWE：

 \tikzset{every picture/.style={line width=0.75pt}} %set default line width to 0.75pt        

 \begin{tikzpicture}[x=0.75pt,y=0.75pt,yscale=-1,xscale=1]
 %uncomment if require: \path (0,300); %set diagram left start at 0, and has height 
 of 300

非常感谢您的支持！

为了说明我的评论：

\documentclass{article}
\usepackage[svgnames]{xcolor}
\usepackage{venndiagram}
\begin{document}
\begin{venndiagram2sets}[shade=LemonChiffon, overlap=1.1cm, labelAB=$A\cap B$, labelNotAB=$\Omega$]
\fillACapB
\end{venndiagram2sets}
\end{document}

如果您想要一些更奇特的东西，那么您可以使用venndiagram包中的一些内部组件来更改每个图表段的颜色，并用粗彩色线条绘制线条部分。

\documentclass{article}
\usepackage[svgnames]{xcolor}
\usepackage{venndiagram}
\begin{document}
\makeatletter
\begin{venndiagram2sets}[overlap=1.1cm, labelAB=$A\cap B$, labelNotAB=$\Omega$]
\setpostvennhook{
\begin{scope}
\clip (\@venn@Ax,\@venn@Ay) circle (\@venn@radius);
\path[ultra thick,draw,red]
   (\@venn@Bx,\@venn@By) circle (\@venn@radius);
\end{scope}
\begin{scope}
\clip (\@venn@Bx,\@venn@By) circle (\@venn@radius);
\path[ultra thick,draw,red]
   (\@venn@Ax,\@venn@Ay) circle (\@venn@radius);
\end{scope}
}
\renewcommand*{\@venn@shade}{Plum}
\fillA
\renewcommand*{\@venn@shade}{LemonChiffon}
\fillB
\renewcommand*{\@venn@shade}{Plum!40!LemonChiffon}
\fillACapB
\end{venndiagram2sets}
\makeatother
\end{document}
