TiKz figure getting cutting off due to its size

Question

I have a paper divided into 2 columns and I am "drawing" on the second column, I am trying to create a linked list there using the code given here: https://tex.stackexchange.com/a/19288/233406 however, my linked list is too big and getting cut off, how can I solve this?

Minimum reproducible example:

\end{tikzpicture}

\end{figure}
\end{document}

Here the list is on the first column so it just passes to the second one but in the original document it is in the second column which just makes it cut Picture of what is happening:

Any help would be appreciated. I don't mind continuing the linked list on multiple lines/rows as long as it is clear, I don't necessarily want to fit it all in the same space as that might be unplausible.

Your figure is too large to stay on one column only and if you scale it it becomes unreadable.

You figure* environment to print it on two columns.

If you would like to scale it:

Answer 2

Mostly off-topic, however it may be useful ...

Your image is to wide that can be for in one column. Consequently, for image you should use figure* float. In cases, that you like image on the bottom of the same page, use stfloats package.

If this is not satisfactory, i.e. that image should be somewhere on a middle of the page, use cute package:

\documentclass[conference]{IEEEtran}
%---------------- Show page layout. Don't use in a real document!
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}
%---------------------------------------------------------------%
\usepackage{lipsum}

\usepackage{tikz}
\usetikzlibrary{arrows.meta,
                chains,
                positioning,
                shapes.multipart}
\usepackage{cuted}
\usepackage{capt-of}

                        (\LN.south west) -- (\LN.north east);
                                     }}, 
                node contents={}},
   arr/.style = {{Circle[length=2mm, sep=0pt -2]}-Stealth},
