Fork of Smiley Face (React and d3)
This example shows a stylized smiley face built with React and D3, rendered as SVG. The face is composed of separate React components for the background circle, eyes, and mouth, all positioned within a centered group. D3's `arc` function generates the mouth path, while the eyes use hardcoded circle coordinates. The code uses React 16 and D3 v6, with styling applied through a simple CSS file.
