I was working with a Sample data which was Geographically distributed. when i was trying to create a Geographical Hierarchy, Some places were not found and some had a close match.
I suggest Lumira should provide us to pic an area from the Map/ By entering details manually. Visualizations with "Not found" data will not be complete. My idea was posted in ideas.sap.com here
PFB of a Geographic Visualization - where i had data related to Europe, West Indies :- but Lumira Din't find a match to these places.
