This example displays a single large yellow circle with a black outline, rendered as a static smiley face head without facial features. Built with React and rendered as SVG, the application creates a 960 by 500 pixel canvas and positions the circle at its center. The code defines an `App` component that returns the SVG element, then mounts it to the DOM using `ReactDOM.render`. The face is drawn using two `<circle>` elements, with the outermost shape filled yellow and stroked black, while a commented-out section hints at future eye placements.
