A grid of 63 randomly generated smiley faces, each rendered as a separate SVG through React components. The faces vary in eye size, eye offset, and mouth dimensions due to JavaScript’s `Math.random()` calls during rendering. The visualization uses d3’s `arc` function to draw the mouth paths and React to compose the face parts (background circle, eyes, mouth) within a shared container. Each face is identical in size and positioning, but the stochastic parameters create a playful, varied collection.
