This example shows a stylized smiley face rendered as a static SVG graphic, composed of a yellow circle, two dark eyes, and a dark mouth. The React component structure separates the face into reusable parts, with `FaceContainer` establishing the SVG and centering transform, while `BackgroundCircle`, `Eyes`, and `Mouth` define the visual elements. The mouth uses a D3 arc generator with a specified inner and outer radius to create a half-circle shape, while the eyes and background circle use simple SVG circle elements. The face is centered within a 960×450 viewport using calculated `centerX` and `centerY` coordinates. React 17 and D3 v7 are used as the primary libraries, with rendering occurring entirely through SVG elements.
