I need to understand this dataset's structure and identify its most important numeric metric, then find the highest and lowest records for that metric. Let me start by examining the dataset structure and available columns: ```json { "action": "tool_call", "reasoning": "The dataset card shows this is polling data about AI usage with 105 rows and 44 columns. Most columns appear to be demographic breakdowns (percentages by age, gender, income, etc.). I need to inspect the actual columns to understand what numeric metrics exist and identify the most important one. The card shows columns like 'Overall', various demographic segments, and question/response fields. Let me inspect the table to see the actual data types and values.", "tool": "inspect_columns", "args": { "table": "raw.polling_on_ai_usage_jul_2026" } } ```
