Define data

cities = pd.read_csv('../../assets/cities.csv', encoding="ISO-8859-1")
population = gv.Dataset(cities, kdims=['City', 'Country', 'Year'])
points = population.to(gv.Points, ['Longitude', 'Latitude'], ['Population', 'City', 'Country'])

tiles = gv.tile_sources.OSM

Plot

tiles.opts(zoom=0) * points.opts(
