control markers using GeoJson

Hi all,

I can plot markers using GeoJson or Marker. I like using GeoJson since I can plot them all at once without a loop, and also I love GeoJson.Tooltip, which looks great. Please see below for an example.

Unfortunately, I can’t figure out how to change the icon, or other properties of the markers when using GeoJson. If I switch to looping and using Marker, I have more control over the markers but the tooltips don’t look as good when specifying a list of values (I get a string representation).

Is there a way to change properties of the markers using the GeoJson method?

data={'type': 'FeatureCollection',
 'features': [{'id': '0',
  'type': 'Feature',
  'properties': {'SCHOOL_NAME': 'Ascension Elementary School',
   'SCHOOL_CODE': 'ACSN',
   'ADDRESS': '5205 New Street',
   'CITY': 'Burlington',
   'PROV': 'ON',
   'POST': 'L7L 1V3',
   'COUNTRY': 'Canada',
   'style': {'markerColor': '#00000000', 'color': '#00000000'},
   'highlight': {}},
  'geometry': {'type': 'Point', 'coordinates': [-79.7491672, 43.371468]}},
 {'id': '2',
  'type': 'Feature',
  'properties': {'SCHOOL_NAME': 'Bishop P. F. Reding Secondary School',
   'SCHOOL_CODE': 'BHRD',
   'ADDRESS': '1120 Main Street East',
   'CITY': 'Milton',
   'PROV': 'ON',
   'POST': 'L9T 6H7',
   'COUNTRY': 'Canada',
   'style': {'markerColor': '#00000000', 'color': '#00000000'},
   'highlight': {}},
  'geometry': {'type': 'Point',
   'coordinates': [-79.86306090000001, 43.530966799999995]}}]}

m = folium.Map(location=[43.342094, -79.803047], zoom_start=12)
folium.GeoJson(data, name='Schools', tooltip=folium.features.GeoJsonTooltip(fields=['SCHOOL_NAME', 'ADDRESS'], localize=True)).add_to(m)
m

Thanks so much for this incredible package.

Hey @Alcampopiano, glad you’re enjoying the package.

I’ve got a PR in for this issue that I have been needing to finish up in #957. Just been quite busy working on a lot of really fun stuff at a new job. I’ll try to get it wrapped up soon.
