Example displays base map but not points

mapboxgl 0.10.2 in a Python 3.8.6 kernel in Jupyter:

Code

with open('mapbox_token.txt','r') as f:
    # Must be a public token, starting with `pk`
    token = f.read().strip()

import os

import pandas as pd

from mapboxgl.utils import create_color_stops, df_to_geojson
from mapboxgl.viz import CircleViz


# 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)

# 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()

I expected to see points on the map, like in the screenshot in the docs:

df looks vaguely reasonable / non-empty:

Also note the UserWarning mentioned in #150 (comment), not sure if it's relevant:

/usr/local/lib/python3.8/site-packages/IPython/core/display.py:717: UserWarning: Consider using IPython.display.IFrame instead
  warnings.warn("Consider using IPython.display.IFrame instead")

What am I missing? Thanks.

examples/notebooks/circle-vector.ipynb is basically the same viz, but constructed differently (it doesn't use df_to_geojson), and it works for me… not sure what the issue is with the df_to_geojson example

[korompaiistvan]

the problem is that it tries to parse 'points1.geojson' as a geojson string itself. you have to save the output of df_to_geojson to a variable and pass that to CircleViz instead. the main example is simply not correct
