This example shows a simple, stylized smiley face rendered as an SVG graphic using React components. The face consists of a yellow circular background with a black stroke, two black eye circles positioned symmetrically, and a curved mouth created with a D3 arc generator. The code imports `arc` from D3 v5 to define the mouth’s path, while React components like `FaceContainer`, `BackgroundCircle`, `Eyes`, and `Mouth` assemble the visual elements. All shapes are drawn declaratively with SVG elements, and the face is centered within a 960 by 500 pixel viewport.
