Fifty randomized smiley faces render in a grid, each with varying eye and mouth sizes, demonstrating how React components can be reused with dynamic props. The visualization is built with React and D3 v5, where the `arc()` API generates the mouth path, and React Fragments group the eye elements. SVG output is produced through a `FaceContainer` that translates the coordinate system to center each face within its 100×100 viewport.
