In the latest iteration of the "Reasonator", you will find the option to
see what items exist in a radius of 15 km around the current item.
Obviously, you will find only those items that have a geo-coordinate. There
are however many of them :) They are everything from cities to amusement
parks like Disney land and its rides.
Essentially the functionality shows what is the result of a query.
The current maps are based on OpenStreetMap and Wikidata. This is a first
iteration of this functionality so we love to hear from you what more and
what else you would like us to do with maps and Wikidata.
