I am running jupyter notebook on a Databricks cluster and attempting to render a map. I tried the example from the documentation to test and it doesn't plot the points. 

  # Load data from sample csv

  data_url = 'https://raw.githubusercontent.com/mapbox/mapboxgl-jupyter/master/examples/data/points.csv'

  df = pd.read_csv(data_url)

  # Must be a public token, starting with `pk`

  token = mapbox_token

  # Create a geojson file export from a Pandas dataframe

  df_to_geojson(df, filename='points.geojson',

         properties=['Avg Medicare Payments', 'Avg Covered Charges', 'date'],

         lat='lat', lon='lon', precision=3)

  # Generate data breaks and color stops from colorBrewer

  color_breaks = [0,10,100,1000,10000]

  color_stops = create_color_stops(color_breaks, colors='YlGnBu')

  # Create the viz from the dataframe

  viz = CircleViz('points.geojson',

          access_token=token,

          height='400px',

          color_property = "Avg Medicare Payments",

          color_stops = color_stops,

          center = (-95, 40),

          zoom = 3,

          below_layer = 'waterway-label'

         )

  viz.show()
