I need to identify the most important numeric metric in this dataset and show its highest and lowest records. Let me start by understanding what metrics are available and their significance. ```json { "action": "tool_call", "reasoning": "I need to understand the dataset's purpose and which metrics are most significant. The overview section will give me context about what this dataset is for and what the key measures represent.", "tool": "read_insight", "args": { "section": "overview" } } ```
