Folium library error in choropleth - python-3.x

Question

Am using folium library with an open data set from kaggle,
map.choropleth(geo_path=country_geo, data=plot_data,
columns=['CountryCode', 'Value'],
key_on='feature.id',
fill_color='YlGnBu', fill_opacity=0.7, line_opacity=0.2,
legend_name=hist_indicator
)
The above part of the code is giving me the following error:
TypeError: choropleth() got an unexpected keyword argument 'geo_path'
When I replace geo_path with geo_data I get this error:
JSONDecodeError: Expecting value: line 7 column 1 (char 6)

Answer 1

Is the issue related to "UCSanDiegoX: DSE200x Python for Data Science"? I took the advice of Cody and rename geo_path to geo_data at the specifications of map.choropleth.
At the git hub repository, take care of using the RAW data, which is in fact a file structured with the format GeoJSON. The first two lines should start like the code provided below
{"type":"FeatureCollection","features":[
{"type":"Feature","properties":{"name":"Afghanistan"},"geometry":
{"type":"Polygon","coordinates":[[[61.210817,35.650072],.....

Answer 2

geo_path doesn't work because it is not a parameter for choropleth. You are correct in replacing it with geo_data.
Your second error is likely due to non-existent or incorrectly formatted geojson file.
From http://python-visualization.github.io/folium/docs-master/modules.html?highlight=chor# your argument for geo_data needs to be a "URL, file path, or data (json, dict, geopandas, etc) to your GeoJSON geometries".
GeoJSON formatted files follow this structure from geojson.org:
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [125.6, 10.1]
},
"properties": {
"name": "Dinagat Islands"
}
}
