Is there a way to make tikz not start in the middle of the page? I've tried the solutions in How to start tikzpicture on top-left of page and Force wide Tikz figure to move left, but neither have worked. It seems only the right half of the page exists. Is it possible to fit more than one image on a page in tikz? If so, how? The attached image is what I'm trying to fit on the page
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\begin{scope}%[xshift=-1e6km]% this does nothing
\node at (0,0) {\includegraphics[width=10cm]{Figure a}};
\end{scope}
\begin{scope}[xshift=0cm, yshift=3cm] % Top left
\clip (0,0) circle (2cm);
\node at (5,3) {\includegraphics[width=25cm]{Figure b1}};
\draw[color=black, thick] (0,0) circle (2cm);
\end{scope}
\begin{scope}[xshift=3cm, yshift=3cm] % Top Right
\clip (0,0) circle (2cm);
\node at (5,3) {\includegraphics[width=25cm]{Figure b2}};
\draw[color=black, thick] (0,0) circle (2cm);
\end{scope}
\begin{scope}[xshift=0cm, yshift=-3cm] % Bottom Left
\clip (0,0) circle (2cm);
\node at (4,2) {\includegraphics[width=25cm]{Figure b3}};
\draw[color=black, thick] (0,0) circle (2cm);
\end{scope}
\begin{scope}[xshift=3cm, yshift=-3cm] % Bottom Right
\clip (0,0) circle (2cm);
\node at (4,2) {\includegraphics[width=25cm]{Figure b4}};
\draw[color=black, thick] (0,0) circle (2cm);
\end{scope}
\end{tikzpicture}
\end{document}

xit has no positioning logic of its own, it just forms part of a paragraph and is only centred if it is in\begin{center}or similar – David Carlisle Nov 10 '22 at 15:15\draw[red] (current bounding box.south west) rectangle (current bounding box.north east);at the end to see precisely where the tikzpicture is located. – John Kormylo Nov 11 '22 at 16:10
