#312 Add markers on folium map

# import libraries
import folium
import pandas as pd

# Make a data frame with dots to show on the map
data = pd.DataFrame({
'lat':[-58, 2, 145, 30.32, -4.03, -73.57, 36.82, -38.5],
'lon':[-34, 49, -38, 59.93, 5.33, 45.52, -1.29, -12.97],
'name':['Buenos Aires', 'Paris', 'melbourne', 'St Petersbourg', 'Abidjan', 'Montreal', 'Nairobi', 'Salvador']
})
data

# Make an empty map
m = folium.Map(location=[20, 0], tiles="Mapbox Bright", zoom_start=2)

# I can add marker one by one on the map
for i in range(0,len(data)):
folium.Marker([data.iloc[i]['lon'], data.iloc[i]['lat']], popup=data.iloc[i]['name']).add_to(m)

# Save it as html
m.save('312_markers_on_folium_map1.html')

  pd is not recognized if we don’t import pandas in the code.
  So before importing folium we write this code
  ‘import pandas as pd’
  then code runs perfectly

    Indeed this was a mistake! Thanks for your feedback, code has been updated.

  for the ‘for’ loop should it not be lat first and then long?

  Hi,

  Thanks for this awesome code.

  I trying to plot from a dataframe with around 160 (longitude and latitude) and m will not display

  Is there a limitation to the length of data that can be plotted ?

  Thanks

    Hi Nadeem,
    I don’t think there is any limitation.
    You could try your code with only ~10 data points to check that it works first.
    Good luck!
