#country_counts(opts = { }) ⇒ Object

Get summed counts by country, optionally constrained by dates and/or country codes. Available options are:

:from

The from date, defaults to the beginning

:to

The end date, defaults to now

:country

The country code, defaults to nil

which means no country code restriction
