  "answer": "Use the UCI Wine CSV to explore 178 observations with a class label and thirteen chemical measurements. The ready-to-chart file selects alcohol and color intensity without standardizing or rescaling either column.",
  "columnNotes": "The first source column is a class identifier, followed by thirteen measurements. The repository describes three cultivars from one Italian region. Its variable table does not supply units for the selected alcohol and color-intensity fields; this resource keeps the original values and does not invent units.",
  "interpretation": "The scatter pairs alcohol with color intensity in source row order. The class code remains in the full CSV, not on either numeric axis. Treating codes 1, 2 and 3 as a continuous measurement would create an arbitrary numerical relationship. For a follow-up, split the paired data by class and compare the within-class pattern with the pooled picture.",
  "limitation": "The sample is a historical classification dataset, not a quality ranking or a representative survey of wines. No tasting score or market outcome is supplied. A visually separated group would not establish that one cultivar is better or that alcohol causes color intensity.",
  "units": "Source values retained; selected measurement units are unspecified in the UCI variable table.",
