使用 Tikz 绘制此路径

在此处输入图片描述

我想用 Tikz 生成这条路径，但我不知道怎么做。我试过用这个，但没有成功（我想使用编译器 LaTeX，而不是 pdfLaTeX，我用的是 OverLeaf。）有人能帮忙吗？

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning, arrows.meta, decorations.pathreplacing}

\begin{document}

\begin{tikzpicture}[>=Stealth, node distance=2cm and 3cm, thick]
  % Nodes
  \node (crocetin) {Crocetin};
  \node[right=of crocetin] (crocinV) {Crocin V};
  \node[right=of crocinV] (crocinIII) {Crocin III};
  \node[below=of crocinV] (crocinII) {Crocin II};
  \node[left=of crocinII] (crocinIV) {Crocin IV};
  \node[below=of crocinIII] (crocinI) {Crocin I};

  % Arrows with labels above
  \draw[->] (crocetin) -- node[above] {$\alpha$} (crocinV);
  \draw[->] (crocinV) -- node[above] {$\beta$} (crocinIII);
  \draw[->] (crocinIII) |- node[near start, right] {$\gamma$} (crocinI);
  \draw[<-] (crocinI) -- node[above] {$\kappa$} (crocinII);
  \draw[->] (crocinIV) -- node[above] {$\epsilon$} (crocinII);
  \draw[->] (crocetin) -- node[left] {$\xi$} (crocinIV);

  % Curved arrows
  \draw[->] (crocinI.south) to[out=-90,in=-90,looseness=1.5] node[below] {$\theta$} (crocetin.south);

  % Brace
  \draw[decorate, decoration={brace, amplitude=10pt, mirror}] 
  (crocinIV.south west) -- (crocinI.south east) node[midway, below=10pt] {$\sigma$};
\end{tikzpicture}

\end{document}

使用tikz.cd（用于简单定位节点并在相邻节点之间绘制箭头）和ext.paths.ortho（用于简单绘制非相邻节点之间的锯齿形箭头）库：

\documentclass[margin=3.141592mm,varwidth]{standalone}
\usepackage{tikz-cd}
\usetikzlibrary{arrows.meta, 
                ext.paths.ortho,    % defined in the tikz-ext package
                }

\begin{document}

    \begin{tikzcd}[
  math mode = false,
arrow style = tikz,
     arrows = {>=Straight Barb, semithick, math mode},
                  ]
Crocetein \rar["\alpha"]      
\dar[shift right=2mm, "\zeta" '] 
\ar[rr, "\gamma", to path={r-ud node[above] {$\gamma$} (\tikztotarget)}]  
    & Crocin V  \rar["\beta"]   
        & Crocin III    \dar[to path={r-rl node[right] {$\theta$} (\tikztotarget)}] \\
Crocin II 
\rar["\varepsilon"]
    \uar[shift right=2mm,"\xi" ']    
    \ar[rr, to path={r-du node[below] {$\delta$} (\tikztotarget)} ]
    & Crocin IV  \rar["\kappa"]  
        & Crocin I;
    \end{tikzcd}
\end{document}
