Now I need to identify other main categorical columns and get their distributions. From the column metadata, I can see several important categorical dimensions I haven't covered yet: beer_ratings.aroma, flavor, mouthfeel, appearance, overall (rating components), and beers.is_seasonal, is_verified, Unrateable, has_pic. Let me get the distributions for the rating component columns first.",
