This interactive visualization renders a smiley face as a full-window SVG graphic using React. The code creates a yellow circle with a black stroke, positioned at the center of the viewport, and adds two smaller circles for eyes at fixed offsets. The implementation uses ReactDOM to render the SVG elements directly into the DOM, with the face dimensions calculated from the browser window’s width and height. The drawing relies on basic SVG shapes—circle elements and a transform group—rather than external data sources or charting libraries.
