This example uses React and D3 v5 to render a stylized smiley face with glasses as an SVG graphic. The face includes a yellow head, eyes, a mouth drawn with the d3 `arc` generator, plus accessories like ears, earrings, hair, a hat, and blue tear paths. The code builds the entire illustration declaratively with React JSX elements, while D3 provides the arc calculation for the mouth shape. All visual elements are positioned using SVG coordinates within a fixed 960 by 500 viewport.
