This example renders a stylized, semi-complete smiley face built from reusable React components. The face includes a gradient-filled background circle, two asymmetric eyes, and a mouth constructed with d3.arc. The teeth component overlays the mouth with a white arc and black dividing lines. All shapes are drawn as SVG elements, transformed into place via a FaceContainer that centers the group. The code imports d3 v7 for arc generation and uses React 18 to compose the modular parts into a single static visualization.
