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