A stylized smiley face rendered as an SVG, built with React and D3 v7. The face uses a yellow-to-orange linear gradient for its circular head, black ellipses for eyes, and a thick arc for the mouth. Two smaller arcs form dimples, positioned symmetrically on either side of the mouth. The code defines reusable arc generators using `d3.arc()`, applies rounded corners via the `cornerRadius` option, and composes the face from separate React components, including a dedicated `Eyes` component.
