A grid of six-by-three randomized faces demonstrates how React components and D3’s `arc` generator can compose static SVG. Each face uses `BackgroundCircle`, `Eyes`, and `Mouth` subcomponents, with `FaceContainer` positioning the group via a `translate` transform. Randomized dimensions—mouth radius and width, eye radius and offset, stroke width—are passed as props from `d3.range`. The rendering is purely declarative, with no data binding or interactions.
