A grid of randomized smiling faces rendered as SVG in React, each face generated with varying stroke widths, eye offsets, eye radii, mouth widths, and mouth radii using D3’s arc generator for the mouth path. The app maps over an array of 18 faces created with d3.range, applying random values per face via Math.random, and renders them through reusable components like FaceContainer, BackgroundCircle, Eyes, and Mouth. The visualization demonstrates component composition and parameterized geometry within a React-D3 integration, with all faces drawn in a static grid.
