问题出在key_on='feature.properties.name'

应为key_on='feature.properties.DISTRICT'

查看JSON文件，查看纬度/经度坐标所映射到的位置。 在世界地图示例中，在其JSON文件中为“名称”，而在旧金山为“ DISCTRICT”

# download countries geojson file
!wget --quiet https://cocl.us/sanfran_geojson -O san_francisco_nh.json

print('GeoJSON file downloaded!')

sf_geo = r'san_francisco_nh.json'

sanfran_map.choropleth(
    geo_data=sf_geo,
    data=nh_countindex,
    columns=['Neighborhood','Count'],
    key_on='feature.properties.DISTRICT',
    fill_color='YlOrRd',
    fill_opacity=0.7,
    line_opacity=0.2,
    legend_name="Neighborhood Crime"
)
