Two versions of a cartoon smiley face are rendered as vector SVG graphics, one small and one large, with randomized eye and mouth sizes. Each face combines React components for its structure—such as `BackgroundCircle`, `Eyes`, and `Mouth`—with D3’s `arc` API to generate the mouth path. The SVG is drawn within a `FaceContainer` that translates a central coordinate group, while the dark stroke and yellow fill come from a basic circle element.
