A yellow face with black-outlined circular head, offset eyes, and a curved mouth is drawn using React components. The SVG rendering is composed of modular `Face`, `BackgroundCircle`, `Eyes`, and `Mouth` components within a `FaceContainer` that centers the drawing. The mouth shape is generated using the `arc()` API from D3 v7. No external data source is used; the face’s dimensions and positions are passed as fixed props from the top-level `index.js` file.
