The german wikipedia has very often maps of some area with a position marker, the map is created from some image and an overlay with the position marker that seems to be created magically from wikidata.
An example of such a map is de:Muro_Lucano
When a hovercards pops up, the position marker is not shown which is IMHO not very helpful. You can reproduce that hovercard in the first line of de:Liste_der_Bischöfe_von_Muro_Lucano.
