This example renders a stylized emoji face as a scalable vector graphic using D3 and React. The face consists of a red circle with a yellow stroke, two black eyes, and a D3-generated arc path for the mouth. The drawing is centered within an SVG canvas using a group transformation, with all geometric properties defined as constants. The code demonstrates integrating D3’s `arc` generator with React components to produce declarative, data-driven SVG shapes in a 960×500 viewport.
