The card lists Question and Response as classifiers with ~16 and ~64 distinct values respectively, but there are many other categorical columns (demographic breakdowns like Gender, Age, Income, Education, Region, Occupation, Race, Employment) that need to be profiled. I'll query to get the top values and their frequencies for each major categorical column.",
