Two identical cartoon faces are drawn as layered SVG circles: an orange background head, two eyes, and an arc-based mouth. A React app renders two `<Face>` components centered in a 960×500 viewport, each composed from reusable subcomponents like `BackgroundCircle`, `Eyes`, and `Mouth`. The code uses React for component composition and the D3 `arc()` generator to define the mouth’s curved path, with all geometry parameterized via props.
