This example displays a cartoon face with a yellow circular background, white eyes with black pupils, and a curved mouth, all rendered as SVG shapes. The face is constructed using React components, including `BackgroundCircle`, `Eyes`, and `Mouth`, with a drop shadow filter applied to the circle. D3’s `arc()` function generates the mouth path, while fixed `<line>` elements form a small nose. Component props control dimensions and colors, and the overall layout centers the face within a 960×500 coordinate system.
