Plot shapely polygon

WebbSince geopandas takes advantage of Shapely geometric objects it is possible to create a Shapefile from a scratch by passing Shapely’s geometric objects into the GeoDataFrame. This is useful as it makes it easy to convert e.g. a text file that contains coordinates into a Shapefile. Let’s create an empty GeoDataFrame. WebbDefining a polygon, shapely.geometry.polygon and then whatever are the coordinates associated with the vertex of the polygon. The polygon will close itself, in this case, 0, 0, 1,1, 1, 0, and then it automatically goes from the last to the first point which closes the polygon, and then you can see the polygon there displayed in Jupyter.
