I need to identify the main categorical columns and find their most common values with frequencies. Let me start by examining the dataset structure. ```json { "action": "tool_call", "reasoning": "The dataset card shows several categorical columns (event, medal, country, event_type, gender, era, is_china). I'll inspect the table to get detailed metadata about all columns to confirm which are categorical and understand their characteristics before querying for most common values.", "tool": "inspect_columns", "args": { "table": "raw.olympic_table_tennis_medals_1988_2024" } } ```
