I need to identify the most important numeric metric in this dataset and show its highest and lowest records. Let me start by examining what numeric columns are available in the dataset. ```json { "action": "tool_call", "reasoning": "I need to see the detailed column metadata to identify numeric columns and understand which would be the most important metric. The card shows Birth year as a temporal axis, but I should inspect all columns to see what numeric data exists.", "tool": "inspect_columns", "args": { "table": "ittf_player_info" } } ```
