    "The question users wanted to answer identifies the comparison task before a chart is chosen. Separate that need from preferences for a particular visual style.",
    "A difficult chart identifies the representation or label that obscures the intended comparison. Clarify measured variables and consider a suitable alternative, without assuming a chart preference demonstrates statistical understanding or analytical validity.",
    "A useful selection example identifies the guidance needed to connect chart structure with the comparison task. Use labelled synthetic data without implying statistical validity from chart preference."

      "question": 1,
      "format": "Optional short text",
      "reason": "Retain the specific point or condition described; avoid replacing it with an unexplained rating."
    },
    {
      "question": 2,
      "format": "Optional written explanation",
      "reason": "Keep context that distinguishes different experiences. A preferred chart does not validate its analysis."

    {
      "question": 3,
      "format": "Optional improvement suggestion",
      "reason": "Keep the suggested change separate from whether it has been tested. Offer examples tied to comparison tasks."
