无限图

Question

我目前正在研究一类特定的图，我必须枚举其所有禁用子图。为此，我必须绘制几个无穷图表，如下所示。

我知道如何绘制基本图形，但我想找到有关如何绘制上述图形的说明或描述。有什么建议吗？

为了绘制基本图形，我使用如下方法：

\documentclass[12pt]{report}
\usepackage{tkz-graph}  
\usepackage{amsmath}
\usepackage{tikz}


\begin{document}

\begin{figure}[h]
    \centering  
    \begin{tikzpicture} 
        \SetGraphUnit{1}                            
        \GraphInit[vstyle=Welsh]
        \begin{scope}[rotate=45]CEAB
        \Vertices[Lpos=45]{circle}{c,b,d,e}
        \end{scope}
        \NOEA[Lpos=90,unit=0.728](b){a}
        %\AddVertexColor{black}{b,d}        
        \Edges(e,b,d,e,c,b,a,c)                 
    \end{tikzpicture}       
    \begin{tikzpicture} 
        \SetGraphUnit{1}                            
        \GraphInit[vstyle=Welsh]
        \begin{scope}[rotate=45]CEAB
        \Vertices[Lpos=45]{circle}{c,b,d,e}
        \end{scope}
        \NOEA[Lpos=90,unit=0.728](b){a}
        \AddVertexColor{black}{a}       
        \Edges(e,b,d,e,c,b,a,c)                 
    \end{tikzpicture}   
    {\footnotesize $n=5$}

    \caption{Two undirected graphs}
    \label{grph:01}
    \centering
    \end{figure}

我做到了！这是我的代码：
