A yellow smiley face with green eyes, rendered as an SVG, uses React to structure the markup and D3’s `arc` generator to draw the nose and mouth paths. The face’s circular head, elliptical eyes, and decorative black eyelashes and smile lines are composed of hard-coded SVG shapes. React 16.9 manages the component, while d3.v5 provides the arc geometry for the mouth and nose, all displayed at a fixed 890×450 viewport.
