Hi, we've just deployed the Kartographer extension on this wiki. It allows you to add interactive maps to pages. See Kartographer help page (please expand and translate it if possible).
Our next step is to add "geoshapes" service to the maps. Geoshapes will allow drawing city/region/country outlines by specifying a wikidata ID. Geoshapes service already allows Graph extension to draw graphs together with interactive information, such as a country with subregions.
