A partially completed smiley face is drawn as a single yellow circle with a black outline on a white background. The example demonstrates a minimal React setup where the SVG element is rendered directly into the DOM via `ReactDOM.render`. The code explicitly defines the circle’s center, radius, fill color, and stroke properties as SVG attributes, though only one of three intended facial features is currently implemented. The visualization relies on React 16.9 and the SVG markup embedded in the JSX component.
