A yellow smiley face is drawn on a black-and-white SVG canvas, with two black eye circles positioned symmetrically on a yellow circular face. The face and eyes are rendered as SVG circles using React 18 and ReactDOM, with coordinates derived from computed center, offset, and radius variables. The stroke width and eye placement are calculated relative to the canvas dimensions, ensuring proportional scaling. The code uses React’s `render` method to inject the SVG into the HTML DOM, with the face centered at 480,250 and eyes offset by 90 pixels horizontally and 50 pixels vertically.
