Fork of Smiley Face Part VI
A grid of eighteen randomly generated smiley faces renders in React, each with varied eye positions, mouth sizes, and stroke thickness. The faces are composed of reusable React components for the background circle, eyes, mouth, and face container, which uses an SVG group transform. D3's `arc` generator creates the mouth path, while React's `range` from D3 produces the array of faces. All rendering uses SVG within a React component hierarchy.
