Fork of Fork of Fork of Fork of Smiley Face Part 5
This example renders a yellow smiley face as an SVG using React components and D3’s `arc` generator for the mouth. The face is centered via a translation, with separate React components for the background circle, eyes, and mouth, each receiving explicit props for positioning and sizing. The visualization demonstrates a modular component approach, with the mouth’s arc path defined by `innerRadius`, `outerRadius`, and start/end angles, while `d3` and `ReactDOM` handle rendering in the browser.
