I want to use Shapely for my computational geometry project. I need to be able to visualize and display polygons, lines, and other geometric objects for this. I’ve tried to use Matplotlib for this but I am having trouble with it.
from shapely.geometry import Polygon import matplotlib.pyplot as plt polygon1 = Polygon([(0,5), (1,1), (3,0), ]) plt.plot(polygon1) plt.show()
I would like to be able to display this polygon in a plot. How would I change my code to do this?

Use:
import matplotlib.pyplot as plt x,y = polygon1.exterior.xy plt.plot(x,y)
Or, more succinctly:
plt.plot(*polygon1.exterior.xy)
