tikz-cd conditional statement with diagrams

Question

Is there a standard way to make a tikz-cd figure consisting of two commutative diagrams appearing side by side with a \Rightarrow in between them? I would like to write a conditional statement with diagrams.

Welcome! Is this a typography question? Just place them both besides each other and place a \Rightarrow between them (in math mode, of course). Should both CDs have the same rows? Do they need braces around them? — Qrrbrbirlbel, Mar 11 '23 at 17:53

@Qrrbrbirlbel thanks for the suggestion, I didn't know figures were stacked horizontally, this is good to know. Then I just changed the baseline parameter suggested by egreg and it worked well! — Carson James, Mar 13 '23 at 06:00

Just place the diagrams side by side, the only problem is the vertical alignment.

\documentclass{article}
\usepackage{amsmath}
\usepackage{tikz-cd}
\begin{document}
\begin{equation}
\begin{tikzcd}[baseline=-axis_height]
A \arrow[r] \arrow[d] & B \arrow[d] \
C \arrow[r] \arrow[d] & D \arrow[dl] \
E
\end{tikzcd}
\implies
\begin{tikzcd}[baseline=-axis_height]
X \arrow[r] \arrow[dr] & Y \arrow[d] \
& Z
\end{tikzcd}
\end{equation}
\end{document}

never knew about that baseline parameter, looks useful for numbered diagrams and such. Thanks! – Carson James Mar 13 '23 at 06:00
