This example renders a smiley face as a static SVG graphic using React and D3’s `arc` generator. A yellow background circle is drawn with a black stroke, and two black eye circles are placed symmetrically on either side of the face’s vertical center. A mouth path is created by the D3 arc, which defines a half-ellipse from a start angle of -π/2 to +π/2, positioned near the bottom-right of the canvas. The code uses React functional components, D3’s `arc()` for the mouth’s path, and SVG elements for circles and paths.
