Feature summary : Wikibase supports uncertainty in coordinates but there is no way to for end users to visualize these. We should visually represent the uncertainty of the coordinate on the map.

I propose either zooming the map different amounts for different uncertainties. Or better we should draw a region representing the zone of uncertainty.

Use case(s) :

• If a user sees a coordinate on an item they can verify that the latitude and longitude are in the right place by looking at the map but unless they have some idea of how big an arcsecond is they will not know if the precision is correct.
• When comparing two coordinates with different precisions and locations a user will not know which one better captures (say) the location of a city.

Benefits (why should this be implemented?):

• Users will be able to better distinguish coordinates of different precision. I think many users don't have an understanding of how big 1 arcsecond is.
• If you look at https://test.wikidata.org/wiki/Q224136 you will see three coordinates with vastly different precisions (so representing vastly different kinds of coordinates) but they look identical. This presents a misleading view of the data.
