Smiley Face Part 1
This example renders a yellow smiley face built from reusable React components, including a circular background, two eyes, and an arc-shaped mouth. The face is centered within an SVG canvas using a translated group element, with proportional sizing based on fixed dimensions and offsets. It uses React components for structure and D3’s `arc` generator to create the mouth path, compositing simple shapes into a cohesive facial expression. The visualization demonstrates a modular approach to SVG drawing with React and D3 in a static, non-interactive composition.
