This example shows a cheerful, cartoon-like face composed of a yellow circle with a black outline, two black eyes, and a curved mouth. Built with React, it renders the face as an SVG using the `d3.arc` API to generate the mouth’s path. The `Face` component combines a `BackgroundCircle`, `Eyes`, and `Mouth` inside a translated group, with all geometry defined by parameters like `offsetX` and `mouthRadius`. The visualization is a minimal, static composition, demonstrating how React components can encapsulate and arrange D3-generated shapes.
