Hi,
Firstly go to /backend/index.php/extensions/index and enable the "Campaigns activity map", then click on it's title to set it up ( /backend/index.php/extensions/campaign-activity-map ).
Next, enable a location service from the extensions area also, say "Ip location - ipinfo.io" and then again click on it's title to set it up ( /backend/index.php/ip-location-services/ipinfoio )
That's pretty much it, you should now see location stats after you send your campaign.
