This example shows a simple yellow smiley face, built with two black-outlined circles as eyes and a large circular face, all rendered as SVG shapes. The face is centered on a 960 by 500 canvas, with the main circle’s radius calculated from the canvas height and stroke width. The code uses React with ReactDOM to define and output SVG elements, and the `index.html` file includes a script that logs React to the console. The visualization is static, displaying only the face and eyes without a mouth.
