title: Folium Heatmap Recursion Error based on location coordinates
body: <p>I am attempting to make a heat map through folium with my data.  Below is my code but I keep getting an error stating: <code>RecursionError: maximum recursion depth exceeded</code> and I have no clue what that means.  Any input?  Below is the code for the heatmap.</p>
  
  <pre><code># Creating a dataframe of the 'month', 'day_of_week' and 'location' day_month = pd.DataFrame(df_criclean[['month', 'day_of_week','location']])
  day_month.sort_values('month', ascending = False).head(10)
  
  # Trying to use folium to make a heatmap of the data I have in 'day_month'
  
  map = folium.Map(location=[42.3601, -71.0589], [enter image description here][1]tiles='cartodbpositron', zoom_start=1)
  HeatMap(day_month['location']).add_to(map)
  </code></pre>
