This example shows a stylized smiley face rendered as an SVG graphic, built with React and D3 v7 in a React component. The face consists of a gold circle for the head, two black eyes, and a mouth drawn using D3’s `arc()` generator to create a half-circle path. Positioning relies on coordinates and offsets computed relative to the SVG’s center, with React managing the JSX elements and D3 handling the mouth’s arc geometry.
