This example shows a stylized, cartoonish face built from layered SVG shapes, featuring gradient-filled cheeks, elliptical eyes, and a mouth with segmented teeth. The face is composed modularly in React components, with each facial feature defined as its own reusable component. The smile and teeth are drawn using d3-shape’s `arc` generator, while the rest of the face relies on standard SVG elements like circles, ellipses, and lines. D3 v7 provides the arc math, and React 18 handles rendering into an SVG container with a fixed viewport.
