? I'm trying to quickly make many simple plots at once. I've tried variations on the following, but it feels a bit hacky.for feature in gdf.iterfeatures():
temp = gpd.GeoSeries(Point(*feat['geometry']['coordinates'][0]), crs=gdf.crs)
ax = temp.plot(figsize=(20, 20), color='red', marker='o', alpha=0.9)
ctx.add_basemap(ax=ax)
fig = ax.get_figure()
fig.savefig('.../out/path/...')
x_coords = np.array([[1, 2, 3], [4, 5, 6]])
y_coords = np.array([[1, 2, 3], [4, 5, 6]])
pygeos.polygons(pygeos.linearrings(x_coords, y=y_coords))
array([<pygeos.Geometry POLYGON ((1 1, 2 2, 3 3, 1 1))>,
<pygeos.Geometry POLYGON ((4 4, 5 5, 6 6, 4 4))>], dtype=object)
