Fork of D3 Playground
A yellow smiley face rendered as SVG using React, with black circle eyes and a curved mouth drawn via the D3 arc generator `d3.arc()`. The face is centered at 960×500 pixels, using fixed offsets for eye placement and a stroke-width of 10 for the outline. The code mixes React elements for circles with a D3-generated path, and loads React 17, ReactDOM, and D3 v7 from CDN. The rendering happens through `ReactDOM.render` into a root div, with no external data source.
