title: Change marker in folium map
body: <p>I have a script to plot multiple points on a map through folium. Is there a way to change the shape of the marker and color?</p>
  
  <p>It doesn't matter if it can be done through the python code or the <a href="http://pastebin.com/2jX5j4FR" rel="noreferrer">html file</a>.</p>
  
  <pre><code>import folium
  import json
  
  
  map_osm = folium.Map(location=[37.7622, -122.4356], zoom_start=13)
  
  geojson = {
      "type": "Feature",
      "geometry": {
          "type": "MultiPoint",
          "coordinates": [[-122.42436302145, 37.8004143219856], [-122.42699532676599, 37.80087263276921]],
      },
      "properties": {"prop0": "value0"}
  }
  
  map_osm.geo_json(geo_str=json.dumps(geojson))
  map_osm.create_map(path='osm.html')
  </code></pre>
