Hi Guys,

so I am working on project, and I am using Unfolding.  
I am trying to add markers from a geoJSON file on the map. This is working fine. But now i want style those markers based on values from an csv datasheet. I have no idea how or if this is possible.

I only used this command:

```auto
List<Feature> countries = GeoJSONReader.loadData(this, "stationen.geojson");
  List<Marker> countryMarkers = MapUtils.createSimpleMarkers(countries);
  map.addMarkers(countryMarkers);

```

Maybe some can help me, thank you in advance

Sebastian

You can style or even create your own marker as documented [here](http://unfoldingmaps.org/tutorials/markers-simple). Give it a try and see if it works for your purpose.
