A playful grid of procedurally generated SVG faces demonstrates component reuse in React. Each face is composed of layered D3 arc-based mouths and simple circle eyes, rendered with randomized parameters for stroke width, eye offset, and mouth size. The code combines React for declarative composition, D3’s `arc` for curved mouth paths, and SVG for vector output, all instantiated via `range` and `Math.random` to vary attributes per face.
