public RepeatedField<int> RatingHistogram { get; }
List of rating counts per rating value (index = rating - 1). The list is
empty if there is no rating. If the list is non-empty, its size is
always 5. Otherwise, an INVALID_ARGUMENT error is returned.
For example, [41, 14, 13, 47, 303]. It means that the
[Product][google.cloud.retail.v2.Product] got 41 ratings with 1 star, 14
ratings with 2 star, and so on.
