I need to identify the categorical columns and count their distinct values. From the dataset card, I can see that `Species` is listed as a classifier with ~3 distinct values. Let me check if there are other categorical columns and get exact counts. ```json { "action": "tool_call", "reasoning": "I need to get detailed metadata for all columns in the Iris table to identify which are categorical and their distinct counts. The card shows Species as a classifier, but I should check all columns to ensure I don't miss any categorical ones.", "tool": "inspect_columns", "args": { "table": "Iris" } } ```
