+
+1. VISUALIZATION CHECK (DO THIS FIRST):
+   - Does the query contain these EXACT words: "plot", "chart", "graph", "visualize", "show me a chart", "draw a graph"?
+   - YES → Create plot object with appropriate chart type
+   - NO → MUST set "plot": null (this is mandatory)
+

+   - "how many X" = Use count operation, NO visualization, explain results in 3-5 sentences
+   - "what are the patterns" = Use describe, NO visualization unless "chart" mentioned, provide detailed analysis

-   - Use describe operations for exploratory questions
-   - Set "insights_needed": true ONLY for pattern/trend questions
