Utiliser le même text width=7mm,inner sep=0pt pour tous les cercles.

Source

\begin{tikzpicture}
    \node[anchor=south west,inner sep=0] (image) at (0,0) {\includegraphics[width=0.9\textwidth]{some_image.jpg}};
    \begin{scope}[x={(image.south east)},y={(image.north west)}]
        % Ces trois commandes suivantes permettent d'afficher une grille qui aide à visualiser les coordonnées des éléments à dessiner:
        \draw[help lines,xstep=.1,ystep=.1] (0,0) grid (1,1);
        \foreach \x in {0,1,...,9} { \node [anchor=north] at (\x/10,0) {0.\x}; }
        \foreach \y in {0,1,...,9} { \node [anchor=east] at (0,\y/10) {0.\y}; }
    \end{scope}
\end{tikzpicture}

Pour faire quelque chose de répétitif sans avoir à changer toutes les coordonnées, par exemple (source):

\begin{tikzpicture}
    \draw [->, very thick] (0, 0) -- (0,-1);
    \tikzset{shift={(0,-1)}}
    \draw [->, very thick] (0, 0) -- (0,-1);
    \tikzset{shift={(0,-1)}}
    \draw [->, very thick] (0, 0) -- (0,-1);
\end{tikzpicture}

%   0
%    +---> x
%    |

\end{tikzpicture}

Le fichier doit avoir l'extension .tikz (source) :

\usepackage{tikzscale}
 
\includegraphics[width=\linewidth]{fichier}

fichier.tikz

\begin{tikzpicture}
% ...
\end{tikzpicture}

Si un message dit que fichier n'est pas trouvé, il est possible d'utiliser resizebox :

\resizebox{\linewidth}{!}{\includegraphics[width=\linewidth]{fichier}}
