What is "user visits" on the admin dashboard?

For user_visits, is it possible for a user to have more than one visit in a day? Or do all visits in a day get chunked into the same row?

A user can only have one entry per day in the user_visits table. The table has a unique index on user_id,visited_at. The posts_read field of the day’s visits will get updated as the user reads more posts.
