答案1
你有想过这样的事情吗?
\documentclass{scrartcl}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\fill[black!80] (-90:1cm) arc (-90:90:1cm)
to [controls={+(180:2.2cm) and +(180:2.5cm)}] (295:3.5cm)
-- ++(0,0.1) to [controls={+(180:0.5cm) and +(270:1cm)}] (-90:1cm);
\fill[red] (0,0) circle (0.6cm);
\end{tikzpicture}
\end{document}

由于您已经发布了 5 个问题,且都没有任何 mwe,为了得到解释,请至少努力在 TikZ-PGF 手册中搜索命令!
\documentclass[a4paper]{book}
\usepackage{tikz}
\tikzset{
pics/mycomma/.style = {code={%
\node[scale=20,xscale=-1]{,};
\node[very thick,red,circle,text width=.1cm,fill=red] at (-.02,.7) {};
}},
}
\begin{document}
\begin{tikzpicture}
\pic {mycomma};
\end{tikzpicture}
\end{document}
