PGF/TikZ

PGF is a lower-level language, while TikZ is a set of higher-level macros that use PGF.

References:

It's a good idea to create an Overleaf project dedicated to previewing TikZ diagrams.

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{% TikZ libraries ----

}
\tikzset{% TikZ global settings ----

}
\begin{document}
\begin{tikzpicture}

% Replace with your TikZ code
\node (tikz) [draw, circle, thick, fill=gray]
    {Ti\textit{k}Z};
