Membangun lokasi marker

# Construct a folium map for school district 1
district1_map = folium.Map(location = district_center, zoom_start = 11)

#create a marker for each school
for row in schools_in_dist1.iterrows():
    row_values = row[1]
    location = [row_values['lat'], row_values['lng']]
    marker = folium.Marker(location = location)
    marker.add_to(district1_map)

    display(district1_map)
