I have a (very) long list of casinos. Each casino has:
boss(a single boss runs from 1 to 50 casinos)
40.642 -73.997 Freddy Queens 40.680 -73.985 Freddy Queens 40.697 -73.949 Freddy Queens 40.651 -73.968 Freddy Queens 40.772 -73.981 Manhattan Michael 40.813 -73.939 Manhattan Michael 40.755 -74.000 Manhattan Michael 40.781 -73.964 Manhattan Michael 40.721 -74.062 Nicole Je. Polizzi 40.750 -74.042 Nicole Je. Polizzi 40.694 -74.090 Nicole Je. Polizzi [... 70,000 casinos for 27,000 bosses ...]
From this data I want to generate a map like this:
Ideally one random color per
boss. In my world the casinos of each boss are supposed to not "overlap" too much with other
bosses, so my final goal is to use this map to find anomalies (casinos that should be transferred to a different
boss because they are clearly in that
boss' "territory"). Boss "territories" do not match any official geographical subdivisions, for all that matters the same problem could be set on Mars (Earth map background would be nice though).
Is there a webapp to which I could feed this data (CSV) and that would show this kind of map? It can look different, for instance monochrome areas would be OK too, as long as it can be used to detect anomalies. A webapp would be the best as many GIS-illiterate people need to quickly check it every once in a while.
I have tried geojson.io but it can not colour points, all points appear equal.
I have tried Mapbox, but it does not seem to support metadata (such as
boss) import, and even less modifying a marker's style based on that metadata.
