Fork of Smiley Face Part V
A modular React application renders a yellow smiley face as a static SVG graphic. The face consists of a yellow circular background with a black stroke, two black eyes positioned by offset coordinates, and a mouth drawn using a D3 arc path. The code splits components into separate ES6 module files, including FaceContainer, BackgroundCircle, Eyes, and Mouth, and uses React Fragments to group the eye circles. D3 v5 provides the arc generator for the mouth’s shape, while React manages the component hierarchy and props for all visual parameters.
