A yellow smiley face rendered in SVG sits centered on a plain white background, composed of a black-outlined circle, two black eyes, and an arc-shaped mouth. Built with React components and D3 v7, the face uses the `arc()` generator to define the mouth path. Functional components like `BackgroundCircle` and `Eyes` accept explicit props for positioning, while a `FaceContainer` wraps the SVG group with a computed transform.
