    "content": "## Distinct Values in Categorical Columns\n\nBased on the column metadata analysis, here are the distinct value counts for categorical columns across the dataset:\n\n### Low-Cardinality Categorical Columns (≤100 distinct values)\n\n**Boolean Flags** (2 values each):\n- `availability.is_in_bottle`, `is_on_tap`, `is_out`\n- `beers.has_pic`, `is_alias`, `is_one_off`, `is_seasonal`, `is_verified`, `Unrateable`\n- `brewers.is_retired`, `has_logo`, `is_out_of_business`, `barrels`\n- `countries.has_brewer`\n- `places.allows_children`, `has_beer_menu`, `has_bottles`, `has_cigars`, `has_flights`, `has_food`, `has_food_menu`, `has_games`, `has_glassware`, `has_intl_shipping`, `has_macros`, `has_mail_order`, `has_patio`, `has_pic`, `has_rare_beers`, `has_real_ales`, `has_seasonals`, `has_singles`, `has_smoking`, `has_taps`, `has_togo`, `has_tv`, `has_wifi`, `is_geo_override`\n\n**Rating Scales**:\n- `beer_ratings.appearance`: 6 distinct values\n- `beer_ratings.mouthfeel`: 6 distinct values\n- `place_ratings.ambiance`: 5 distinct values\n- `place_ratings.value`: 12 distinct values\n\n**Other Low-Cardinality Categoricals**:\n- `places.currency`: 2 distinct values\n- `places.rating_text`: 4 distinct values\n- `places.comments`: 38 distinct values\n- `users.user_type`: 4 distinct values\n- `beer_styles.category`: 4 distinct values\n- `beer_styles.srm_range`: 13 distinct values\n- `beer_ratings.language`: 76 distinct values\n\n### High-Cardinality Categorical Columns (>100 distinct values)\n\n**Administrative/Notes**:\n- `beers.admin_note`: 5,668 distinct values\n- `brewers.admin_note`: 824 distinct values\n\n**Geographic/Postal**:\n- `availability.postal_code`: 7,269 distinct values\n- `places.postal_code`: 44,391 distinct values\n- `brewers.zip_code`: 27,311 distinct values\n\n**Names and Descriptions** (very high cardinality, essentially text fields):\n- `beer_styles.name`: 167 distinct values\n- `beer_styles.description`: 130 distinct values\n- `beers.name`: 1,195,279 distinct values\n- `beers.name_plain`: 1,363,029 distinct values\n- `beers.description`: 751,252 distinct values\n- `beers.tags`: 275,809 distinct values\n- `brewers.name`: 59,008 distinct values\n- `brewers.name_plain`: 41,578 distinct values\n- `countries.name`: 235 distinct values\n- `countries.code`: 292 distinct values\n\nThe dataset contains a mix of true categorical columns (boolean flags, rating scales, language codes) with low cardinality suitable for grouping and analysis, alongside high-cardinality text fields (names, descriptions, postal codes) that are better suited for search and filtering than categorical analysis."
