A smiling face composed of SVG shapes is rendered centered in a 960×500 viewport. Yellow circles form the head and eyes, an ellipse serves as the nose, and a mouth is drawn using a D3 arc path generator. The visualization is built with React components, using JSX to declare SVG elements and the `d3.arc()` API to define the mouth’s curvature. All positions are calculated from center coordinates and fixed offset constants, with a black stroke outlining the face.
