This example shows a large, stylized smiley face rendered as a pink circle with green outline, eyes, and an arc-shaped mouth, all positioned within a spacious SVG canvas. The visualization uses React to define the component structure and D3’s `arc` API to generate the mouth path, with coordinates and dimensions set via fixed constants. D3 v7 and React are loaded via CDN, and the face is drawn using SVG circle and path elements rather than complex data binding.
