plot multiple rectangles/circles in the same frame, hold on

Hi I want to plot any desired number of circles in one plot for a billiard game. Creating each rectangle for itself isnt so handy because I would like to plot theoratically an infinite number of balls.

Thats why I wondered if its possible to plot the same object/rectangle at different positions at the same time. I tried using hold on. But it shows still only one ball.

hold on
for k1 = 1:length(t)    %t = timestep
    for k2 = 1:4:num_variables      %this loop iteration should pick and plot one ball, ...
        % which then needs to be held until all balls are plotted and a new timestep can be started
        
        %k2 refers to x-value column, k2+2 refers to y-value column 
        set(redball,'Position',[y_total(k1,k2)-r, y_total(k1,k2+2)-r, 2*r, 2*r]);
    end 
   

How would you solve this?

Thanks in advance!!

To plot them you can specify the centers and use markers, increase the size of markers. Have a look on plot.
