# Reducing space in graph of tikz

I have the following graph on Tikz.

\begin{tikzcd}

&                                          &                                        &                                                     & \overline{\varnothing}                                          &                                          &                             &                                          &                             \\

I would like to know if there is any way to reduce it so that it is more similar to the following image:

I don't want to change the visuals, just make it look more compact in the document. I made this graph with the help of https://tikzcd.yichuanshen.de/

• \begin{tikzcd}[column sep=small,row sep=small]. You can set column sep and row sep to any length, e.g., column sep=3mm,row sep=3mm May 4 at 20:54
• Thank you very much, they turned up perfectly. I think I don't have the level to rate your answer for now, but I will rate it for future viewing. May 4 at 21:05
