This example shows a stylized cartoon face rendered as SVG, with a yellow circular background, two eyes, and a mouth built from a D3 arc. The face is centered on a 960 by 500 canvas using React components that compose `FaceContainer`, `BackgroundCircle`, `Eyes`, and `Mouth`. The code uses React 16.9, ReactDOM, and D3 v6’s `arc` generator to define the mouth’s path. All facial features are parameterized via props, allowing the face’s dimensions and positions to be adjusted independently.
