Here's `an example <{%22table%22:%22roadside_attraction_characteristics%22,%22column%22:%22characteristic_id%22,%22value%22:%221%22}>`__.

Executes a SQL query that returns a count of the number of rows matching
each unique value in that column, with the most common ordered first.

You can pass multiple ``_group_count`` columns to return counts against
unique combinations of those columns.

Pagination by continuation token - pass the token that was returned in the
``"next"`` property by the previous page.
