I need to identify the main categorical columns and find their most common values with frequencies. Let me start by examining the column metadata to understand which columns are categorical. ```json { "action": "tool_call", "reasoning": "I need to identify the categorical columns in both tables. The card shows Rank, Assoc, Gender, and Name as potential categorical columns. I'll inspect the columns of both tables to understand their types and cardinality, which will help me determine which are the main categorical columns to analyze.", "tool": "inspect_columns", "args": { "table": "raw.ittf_rankings" } } ```
