title: Adding markers to a Folium Map
body: <p>I'm trying to add markers to a Folium Map of a city using the latitudes and longitudes from columns of a Pandas dataframe. But, all I get is an empty map as a result and no errors. </p>
  
  <p>I've tried it using a for loop to iterate over the rows of the datframe and adding the markers for each item into the map, but that doesn't seem to work.</p>
  
  <pre><code>f_map = folium.Map([-35.2809, 149.1300], zoom_start=12)
  for index, row in dataframe.iterrows():
      folium.Marker([row['location.lng'], row['location.lat']], popup=row['name']).add_to(f_map)
  f_map
  </code></pre>
  
  <p>I'm a novice with Folium. Can anyone tell me what I'm doing wrong!</p>
