A fork of the classic "Cat smiley" example renders a cartoon cat face with multiple SVG shapes. The visualization uses React to structure the component and d3.arc to generate paths for the cat's mouth, eyes, and ears. The face is drawn with circles, ellipses, and lines, all positioned using inline SVG attributes within a single `<svg>` element. The example demonstrates combining React's declarative rendering with D3's geometry helpers to create a static, stylized graphic on a fixed 850×455 canvas.
