I need to identify the most important metric and category in this dataset, then show how they relate. Let me start by examining the available columns and understanding what metrics and categories exist. ```json { "action": "tool_call", "reasoning": "I need to understand the column structure and semantic roles to identify the most important metric and category. The card shows columns but I should inspect them to see their semantic roles and understand which are measures vs dimensions.", "tool": "inspect_columns", "args": { "table": "ittf_rankings" } } ```
