In jupyter notebook, I'm trying to make draw a shape (say circle) on some location points plotted on map as shown below:
# df is a pandas dataframe with coloumns 'lon' & 'lat'
points = gis.content.import_data(df)
# cen_lon, cen_lat are center longitude and latitude respectively.
I want a circle/polygon should appear, which encircles the points of df upto some radius r
