This example shows a yellow smiley face drawn with SVG circles, centered and scaled to fill the browser window. The face’s head, eyes, and mouth are positioned using React components, with the mouth omitted from the final render despite being defined in the code. React 16.9 and ReactDOM render the SVG elements, while JavaScript variables compute the window dimensions and facial feature offsets. The styling and stroke widths are set inline within the JSX markup, and the code is intentionally left as a fork of a prior smiley face implementation.
