This example shows a simple smiley face rendered as a static SVG graphic, composed of a yellow circular head, two white eyes with green irises, and a black smile. Built with React and D3, it uses d3.arc() to generate the paths for the head, eyes, irises, and mouth, with each shape positioned via SVG <g> transforms. The code defines arcs with explicit inner/outer radii and start/end angles, then renders them as <path> elements within a 960x500 SVG canvas.
