LaTeX 中的圆形图

如何在 LaTeX 中绘制下图？但我不想在顶点处放黑点，而是想放数字。

欢迎！这是一个重复的问题，这里是一个重复的答案。箭头确实沿着一个圆圈。

\documentclass[border=3mm,tikz]{standalone}
\usetikzlibrary{arrows.meta,bending,calc,intersections}
\begin{document}
\begin{tikzpicture}[nodes={circle},
 pics/circular arc/.style args={from #1 to #2}{code={
 \path[name path=arc] 
  let \p1=(#1),\p2=(#2),\n1={Mod(720+atan2(\y1,\x1),360)},
  \n2={Mod(720+atan2(\y2,\x2),360)},
    \n3={ifthenelse(abs(\n1-\n2)<180,\n2,\n2+360)}
  in (\n1:\pgfkeysvalueof{/tikz/circular diagram/radius}) arc(\n1:\n3:\pgfkeysvalueof{/tikz/circular diagram/radius});
 \draw[pic actions,
    name intersections={of=#1 and arc,by=arcstart},
    name intersections={of=#2 and arc,by=arcend}] 
    let \p1=(arcstart),\p2=(arcend),\n1={Mod(720+atan2(\y1,\x1),360)},
     \n2={Mod(720+atan2(\y2,\x2),360)},

  node[auto,midway,swap]{$\pgfkeysvalueof{/tikz/circular diagram/label}$};
