Smiley Face Part 1
This example demonstrates a modular React-based smiley face composed of separate components for the background circle, eyes, and mouth. The face is centered within an SVG canvas, with the mouth drawn using a d3 arc path with inner and outer radii. The visualization highlights a component-driven approach, where each facial feature is a reusable React function component, and the SVG rendering is managed through JSX. The code uses d3.v6 for the arc generator and React 16.9 for the component structure, with all elements rendered as SVG.
