You may have to do this with two plot commands,

one to create a red line

one to create a gigantic square, which you can do it by plotting a single point in the position of the square.

you have to change the plot marker to some that produces a square, I'm not sure if the square is fulled or not. and increase the font size or marker size

search for plot and find marker and .... properties.

Give it a try

or just use the rectangle function...
