Fork of Smiley Face Part V
A smiling face is drawn in SVG, assembled from modular React components for the yellow circular background, two eyes, and a mouth. The shape is centered within a fixed 960 by 500 viewport and uses reusable components with configurable props for positioning and sizing. The mouth is generated with the D3 `arc` generator, while other elements are plain SVG circles within a transformed group. The project demonstrates splitting React components across files with ES6 modules and uses React Fragments to group the eyes without extra DOM nodes.
