答案1

作为基于我的一个旧答案的起点。在图中，您需要插入正确的变量：

\documentclass[margin=3.1415692mm,varwidth]{standalone}
\usepackage{tikz-cd}
\usetikzlibrary{arrows.meta, bending}
\usepackage{amssymb}

    \begin{document}
    \[
\begin{tikzcd}[sep=large,
               every arrow/.append style = {-{Straight Barb[bend]}},
%               every label/.append style = {font=\normalsize}
               ]
                &   W \ar[d,"f"]
                      \ar[dl,bend right]
                      \ar[dr,bend  left]    &                   \\
B 
\ar[d,"xxx" ']  &   (A\times B)
                    \ar[l,"xxx" ']
                    \ar[r,"xxx"]
                    \ar[d,"xxx"]            &   A
                                                \ar[d,"xxx"]    \\
Y               &   X\times X       
                    \ar[l,"xxx" ']
                    \ar[r,"xxx"]            &   X               \\
\end{tikzcd}
    \]
\end{document}

我发现了这个在线编辑器，抹茶，是一款非常方便的快速排版 Latex 图像的工具。它具有直观的图形界面，使用起来非常愉快，并且可以导出为 Tikz 代码或图像。

为了获得灵感，这是我快速制作的图像的快速版本。

自动生成的 Tikz 代码如下：
