The card shows 4 measures (SepalLengthCm, SepalWidthCm, PetalLengthCm, PetalWidthCm) and 1 classifier (Species with ~3 distinct values), plus a gold table with species-level aggregations. I should inspect the actual data to see the distribution of species, the ranges of measurements, and any patterns that would suggest compelling analytical questions. Let me start by querying the gold table to see the species breakdown and measurement statistics.",
