A stylized smiley face rendered as an SVG, centered on a yellow circle with black strokes for the head, eyes, and a curved mouth, plus a small dimple arc to the side. Built with React and D3 v6, the code uses `d3.arc` to generate the mouth and dimple paths, `d3.line` for the winking eye, and computes geometry from fixed dimensions to position all elements relative to the viewport center.
