This example shows a stylized emoji-like face rendered as an SVG, featuring a gold circle head, two dark eyes, and a curved smile. The face is built using React components and D3’s `arc` generator to create the mouth path. Key layout values like eye offset, radius, and mouth dimensions are defined as constants. SVG groups with `translate` transforms position the elements relative to the center, while D3 v7 and React 17 are loaded via CDN. The rendering approach combines declarative JSX with D3’s geometry helpers for the mouth curve.
