A grid of 18 randomly generated smiley faces renders in SVG via React components, each with varied stroke widths, eye offsets, eye radii, and mouth dimensions produced by Math.random(). The visualization demonstrates modular React component composition across files, using ES6 imports and React Fragments to assemble facial features. D3’s arc() API generates the mouth path for each face, while the ReactDOM render and range() from d3 populate the array of faces.
