I need to find the distinct value counts for categorical columns. Let me start by querying the metadata that tracks column statistics. ```json { "action": "tool_call", "reasoning": "The inspect_columns results show that distinct_count and approx_distinct_count columns exist in the metadata. I need to query the actual metadata tables to get distinct counts for categorical columns. Based on the dataset card, analytics.column_overview contains distinct_count. Let me query that for categorical columns.", "tool": "query_sql", "args": { "sql": "SELECT table_name, column_name, phys_type, semantic_role, rough_kind, distinct_count, approx_distinct_count FROM analytics.column_overview WHERE rough_kind = 'categorical' ORDER BY distinct_count DESC NULLS LAST LIMIT 50", "purpose": "Get distinct value counts for all categorical columns, ordered by cardinality" } } ```
