filter = data['name'] == 'Zambia'

data_filter = data[filter]

data_filter

The filtered data output could be seen:

Draw just one pinpoint, but with the bar graph

The next code creates the map with a pinpoint which contains a bar graph element.

# import the library

import folium

# Make an empty map

m = folium.Map(location=[20,0], tiles="OpenStreetMap", zoom_start=2)

# add marker one by one on the map

for i in range(0,len(data_filter)):

   folium.Marker(

      location=[data_filter.iloc[i]['latitude'], data_filter.iloc[i]['longitude']],

      popup=popup,#data_filter.iloc[i]['name'],

      lazy=True

   ).add_to(m)

# Show the map
