This example displays a yellow smiley face with black-outlined circles for the background, eyes, and a curved mouth, centered on a 960 by 500 SVG canvas. Built with React components, the visualization uses D3’s `arc` API to generate the mouth path, while ES6 destructuring passes the radius and stroke width props to the background circle. The face is positioned using SVG’s `transform` translation with a fixed center point, and the code renders via ReactDOM into the `#root` div.
