A stylized smiley face is drawn in SVG, with a circular face, two eyes, and a mouth. The face uses a white-to-black linear gradient, while the stroke and accent features use contrasting gradients and a khaki color. The example is built with React for component rendering and D3 v7’s `arc` API to generate the mouth path. All shapes are positioned using hardcoded constants for center, offsets, and radii, with a static SVG canvas set to 960 by 500 pixels.
