Let's Make a Face Part I
Ten randomly generated cartoon faces fill the screen, each a yellow circle with two eyes and a curved mouth. The example shows how to compose reusable SVG components in React and D3 to build a static visual. React renders each face from modular parts like `BackgroundCircle`, `Eyes`, and `Mouth`, while D3’s `arc` generates the mouth path. Random values for eye and mouth size give each face a unique expression.
