Smiley Face Part 1
This example displays a grid of 18 randomly generated smiley faces, each rendered as an SVG with a yellow background circle, two eyes, and a curved mouth. Using React components for the face parts and D3’s arc generator for the mouth path, the code applies random values to stroke width, eye offsets and radius, and mouth dimensions, creating varied expressions. The faces are composed via nested components like FaceContainer, BackgroundCircle, Eyes, and Mouth, all assembled and rendered through ReactDOM.
