Antwort1

Als Ausgangspunkt basierend auf einer meiner alten Antworten. Im Diagramm müssen Sie die richtigen Variablen einfügen:

\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}

Bildbeschreibung hier eingeben

Antwort2

Ich habe diesen Online-Editor gefunden,Matcha, ein sehr praktisches Tool zum schnellen Setzen von Bildern für Latex. Es verfügt über eine intuitive grafische Benutzeroberfläche, mit der man sehr angenehm arbeiten kann, und kann entweder als Tikz-Code oder als Bild exportiert werden.

Zur Inspiration hier eine Schnellversion Ihres Bildes, die ich schnell zusammengebastelt habe.

Mathcha-Beispiel

Und der automatisch generierte Tikz-Code:

\tikzset{every picture/.style={line width=0.75pt}} %set default line width to 0.75pt        

\begin{tikzpicture}[x=0.75pt,y=0.75pt,yscale=-1,xscale=1]
