I am trying to build countries vs number of sessions/visits view in the analytics project. However, I could get country vs number of occurrences(which includes multiple requests in a single session) but not number of unique sessions. How can I build this view?
Could you elaborate a definition for the session metric you are referring to?
In general, you may want to use just the metric Unique Visitors with the Countries dimension. If you want to know how many page views on average every visitor views, you can create a calculated metric = Page Views / Unique Visitors and add it to the table. Similarly, if you want to know how many pages every visitors view within a visit, create a metric = Page Views / Visits.
