This example shows a yellow emoji-like face with two eyes and a mouth, rendered as an SVG graphic centered on a 960×500 canvas. The code combines React for component structure with D3’s `arc` generator to create the mouth shape, while simple SVG `circle` elements handle the face and eyes. The face is positioned inside a `<g>` element using a `translate` transform, and styling is applied via SVG attributes such as `fill`, `stroke`, and `strokeWidth`.
