我怎样才能生成类似该图的线图？

我正在尝试使用 Tikz 包绘制左侧的图形。有人有模板可以分享吗？非常感谢，

在此处输入图片描述

为了制作左侧图形，我们可以从图像中定义一个命令来制作主体图标，对于线条，使用arrow和arrow.meta库。

输入

\documentclass[border = 5pt]{standalone}

\usepackage{tikz}
\usepackage{graphicx}
\usetikzlibrary{positioning,arrows, arrows.meta}

\newcommand{\body}{
    \includegraphics[scale=0.036]{body.png}
}

\begin{document}
    
    \begin{tikzpicture}[every node/.style={scale=0.3}]
        % Drawing the main axis with 10 body icons
        \draw[<->] (0,6) |- (6.5,0);

            \node[left=0.15] (bodies) at (0,\b){\body};
            \node[left=0.35] at (0,\b){\textbf{\textsf{UC-\n}}};
        }
        % Drawing the dotted lines
        \foreach \l\s in {1/entry,5.5/exit}{
