This example renders a smiling face using React and SVG, with the D3 shape API’s `arc()` function generating the mouth path. The face consists of a yellow circle with a black stroke for the head, two white eye circles positioned symmetrically, and a curved mouth created from an arc with inner and outer radii. All elements are centered via a translated group, and the layout uses hardcoded dimensions (960×500) without any data binding or interactive behavior.
