A grid of smiley faces fills the screen, each face rendered as a yellow circle with black outlines, eyes, and a curved mouth. Faces are generated procedurally via React components, with randomized stroke widths, eye offsets, eye radii, and mouth dimensions creating subtle variation across the array. The visualization uses React 17 and D3 v6, leveraging d3.arc for mouth paths and d3.range to create the 18-face layout, with all elements drawn as SVG.
