A cheerful yellow face with black eyes and an animated eyebrow appears on a red background. The visualization uses SVG shapes—circles for the face and eyes, rectangles for eyebrows, and a path for the mouth—built with D3.js v5 within a React framework. The right eyebrow animates via D3’s `.transition().duration()` chaining, moving up and down over 1.5-second intervals, while the static left brow and mouth stay fixed.
