我正在尝试使用重新创建以下草图tikz。我发现这个例子绘制圆形，但将其与网格结合起来生成下面的图片有点困难。
我怎样才能在乳胶中生成上图？
\documentclass[tikz, border=2pt]{standalone}
\usetikzlibrary{calc}
\usetikzlibrary{math}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{tikzpicture}[line width=3pt]
\tikzmath{
\r = 3;
\R = (pi * \r + \r)/2;
\l = sqrt(pi)/1.5 * \r;
}
\coordinate (O1) at (0, 0);
\coordinate (O2) at ($(O1)+(1.5*pi*\r, 0)$);
\coordinate (O3) at ($(O1)+(3*pi*\r, 0)$);
\filldraw[fill=lightgray, draw=black] (O1) circle [radius=\r];
\draw (O2) circle [radius=\r];
\draw (O3) circle [radius=\r];
\draw[fill=red, draw=black] (O2) ++(-.65*\r, -7/6*\r) rectangle ++(\l, -\l);
\draw[fill=red, draw=black] (O3) ++(-2.3*\r, -0.5\r) rectangle ++(\l, -\l);
\end{tikzpicture}
\end{document}
使用该示例，我更改了代码，但是有一条红线穿过圆心，我无法将其删除，而且我不知道如何向\draw标签命令中添加文本。
更新： 只是为了说明并展示结合@marmot 和@Zarko 的当前问题，在编译以下答案之后：

答案2
这是针对“填充网格”的提议。
\documentclass[tikz, border=2pt]{standalone}
\usetikzlibrary{calc,positioning}
\usetikzlibrary{math}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{tikzpicture}[line width=3pt,font=\sffamily]
\tikzmath{
\r = 3;
\R = (pi * \r + \r)/2;
\l = sqrt(pi)/1.5 * \r;
}
\tikzset{gnode/.style={fill=gray!50,draw=gray!50,line width=1pt},
bnode/.style={fill=black,draw=black,line width=1pt}}
\matrix [column sep=1pt,nodes={minimum size=5mm,rounded corners=2pt}] (mat) {
\node [gnode] {}; & \node [gnode] {1};
& \node [gnode] {2}; & \node [gnode] {3};\\
\node [gnode] {A}; & \node [bnode] {};
& \node [bnode] {}; & \node [draw=purple,fill=gray!50,line width=1pt] {}; \\
\node [gnode] {B}; & \node [bnode] {};

};
\node[above=0pt of mat] {Customers};
\path (mat.south west) -- (mat.north west)
node[midway,sloped,above] {Dishes};
\end{tikzpicture}
\end{document}
答案3
只是为了运动和练习定位选项，甚至对于矩阵来说，并且感谢2个很好的答案，我制作的代码添加了一些文本操作和结构化编码实践，这样对于像我这样的初学者来说就不会那么晦涩难懂了。
