A cheerful cartoon face constructed from basic SVG shapes—a yellow circle, black eyes, and rectangular eyebrows—renders on a neutral background. An eyebrow group animates upward and back down using chained `transition` calls with `duration(2000)`, creating a playful expression. The face’s components are positioned via `d3.arc` for the mouth, while circles and rects are placed with explicit `cx`, `cy`, and `x` attributes. D3 v6 selections and attribute manipulation drive the scene, with a centered `g` transform aligning all features.
