Python : Folium map not appearing

Question

I am trying to map some data for Canada using Folium. However, in the end, I am getting whitespace as an output with no error message. My code is below.

import folium
import json # or import geojson

with open("geo.json") as json_file:
    json_data = json.load(json_file) # geojson file

# create a plain world map
can_map = folium.Map(location=[56.1, 106], zoom_start=2, tiles='Mapbox     
Bright')

c2 = {
  'Alberta': 144284.48,
  'British Columbia': 141222.06000000017,
  'Manitoba': 134337.96999999994,
  'New Brunswick': 115727.67000000001,
  'Newfoundland': 6885.140000000001,
  'Northwest Territories': 91755.44000000002,
  'Nova Scotia': 80136.18000000005,
  'Nunavut': 1506.4300000000014,
  'Ontario': 352263.50999999983,
  'Prince Edward Island': 28742.2,
  'Quebec': 138658.87999999998,
  'Saskachewan': 177314.26000000013,
  'Yukon': 74404.80000000003
}

# generate choropleth map using the total immigration of each country to Canada from 1980 to 2013
can_map.choropleth(
  geo_data=json_data,
  data=c2,
  columns=['Province', 'Profit'],
  key_on='feature.properties.name',
  fill_color='YlOrRd', 
  fill_opacity=0.7, 
  line_opacity=0.2,
  legend_name='Canada data'
)

# display map
can_map

The json file I am using can be found here

Answer 1

Your code works for me in a Jupyter notebook as is:

For a script, you need to call the save method, like so:

can_map.save('index.html')

Answer 2

Re-run the code in Firefox and it should render in Jupyter notebook.
When you save the map in another browser that saved file should open properly even if it appears as a white cell initially.
