Fork of Smiley Face Part-3 (React and d3)
This example shows a smiling face rendered as an SVG using React components and D3’s arc generator to draw the mouth. The face consists of a yellow circle for the head, two black eyes, and a curved mouth path created with the `arc()` function from `d3-shape`. The code uses React’s JSX syntax and template literals for the SVG group’s `transform` attribute, positioning elements relative to the center. D3 version 6 is loaded alongside React 16, with all geometry constants defined explicitly in JavaScript.
