This example shows a simple, stylized face built from SVG shapes, including yellow circular background, two black-outlined eyes, and a graphic mouth, all rendered inside a D3-created SVG canvas. It is a React application that uses D3's `arc` API to generate the mouth path and organizes the face components into separate React modules. The `FaceContainer` component defines the SVG element, and its children, such as `BackgroundCircle` and `Eyes`, are positioned using passed-in coordinates and radii.
