The result is..

Try isolating the problem. Instead of plotting in a tkinter window, let pyplot draw a window for the plot. If you plot has wide margins you know this is something going on with geopandas. If the plot looks find in a pyplot then there is something going on with tkinter and the layout.

If this is a tkinter layout problem I would put the plot canvas in a frame with a border so you can see the edge of the plot canvas. Is the wide margin inside our outside the frame?

Try to isolate the issue. Instead of charting in a tkinter window, let pyplot create a plot window.
