Smiley Face Part1
This example draws a green smiley face in an SVG using React for structure and d3.arc to generate the mouth path. Fixed coordinates position two black circles as eyes and a filled circle as the head, while an arc with inner and outer radii creates the smile. The rendering relies on React’s createElement and ReactDOM.render, with D3 v7 providing the arc generator, all within a 960-by-500 viewport.
