This example shows a stylized cartoon face constructed from SVG shapes, rendered in a React component. The face consists of a yellow circular background with a black stroke, two eyes, and a mouth created using the d3 `arc` function to draw a semicircular path. The React component system is used to assemble the face from smaller reusable parts like `BackgroundCircle`, `Eyes`, and `Mouth`, with coordinates and dimensions passed as props to position each element.
