Exercise instructions

Find the centroid for each council district and store it in a new column, center in the districts_and_permits GeoDataFrame.
Iterate through districts_and_permits and add a marker at each district's center. Remember to reverse the coordinate pair.
Create popups within your for loop to display the district number and the count of permits issued.
Add the markers to your map with .add_to() and display it.

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

# Create center column for the centroid of each district
districts_and_permits['center'] = districts_and_permits.____.____

# Build markers and popups
for row in districts_and_permits.iterrows():
    row_values = row[1] 
    center_point = row_values[____]
    location = [center_point.____, center_point.____]
    popup = ('Council District: ' + str(row_values[____]) + 
             ';  ' + 'permits issued: ' + str(row_values[____]))
    marker = folium.Marker(location = location, popup = popup)
    marker.____(m)
    
# Display the map
display(m)
