Why I can zoom on Paris ? Why the zoom is limited ?
I found the solution, in
glad you found it! Do note that 30 is a very precise zoom level. Most maps out there usually only go to level 20-22 (like maps from google, bing, yahoo,...). Right now the zooms of the default map of Kibana do not go deeper than level 10 either. So zoom level 30 is a little extreme
FYI, I also linked your post here to https://github.com/elastic/kibana/issues/7882. From your screenshot, the dots look really small. This is because the geohash aggregation (performed by elasticsearch) is too precise for that zoom level.
