投影仪中的图表

Question

我必须为在 beamer 中进行的演示绘制一个图表，图表的节点如下图所示。

是否可以在 Latex 中制作带有此类节点的图形？我该如何绘制它们？

@EvaMGG，

我不知道这是否适合你的目的，但你可以尝试一下tikz

\documentclass[border=5pt,tikz]{standalone}
\usepackage{xcolor}
\usepackage{tikz}

\begin{document}
    
    \definecolor{greenfilling}{RGB}{213,232,212}
    \definecolor{greenoutline}{RGB}{143,187,119}
    \definecolor{greyfilling}{RGB}{245,245,245}
    \definecolor{greyoutline}{RGB}{147,147,147} 

    \begin{tikzpicture}
        \draw (0,0) circle[radius=1cm] node {$_{0}B_{2}$};
        \draw[fill=greenfilling, draw=greenoutline] (-0.75,0) circle[radius=0.375cm] node[red, font=\tiny] {$\xi$};
        \draw[fill=greyfilling, draw=greyoutline] (0.75,0) circle[radius=0.375cm] node[font=\tiny] {\textcolor{red}{$C:0$}\textcolor{blue}{$/2$}};
    \end{tikzpicture}
    
\end{document}

对于动画，你可以尝试这个：

\documentclass{beamer}

\usepackage{tikz}
\usepackage{xcolor}

\definecolor{greenfilling}{RGB}{213,232,212}
\definecolor{greenoutline}{RGB}{143,187,119}
\definecolor{greyfilling}{RGB}{245,245,245}
\definecolor{greyoutline}{RGB}{147,147,147} 

\begin{document}
    \begin{frame}{test}
        \begin{center}
            \begin{tikzpicture}
                \node[draw=black, circle, minimum size=4cm] at (0,0) {$_{0}B_{2}$}; \pause
                \node[fill=greenfilling, draw=greenoutline, circle,  minimum size=1.5cm] at (-1.5,0) {\textcolor{red}{$\xi$}}; \pause
                \node[fill=greyfilling, draw=greyoutline, circle,  minimum size=1.5cm] at (1.5,0) {\textcolor{red}{$C:0$}\textcolor{blue}{$/2$}};
            \end{tikzpicture}
        \end{center}
    \end{frame}
\end{document}
