Smilie Face 1
A smiling face is drawn as a collection of SVG shapes, with a pink circle for the head, two black circles for eyes, and a mouth formed by an arc path. The graphic is centered on an 960 by 500 canvas. The visualization is built using React to render SVG elements, and the `d3.arc` API generates the mouth shape’s path, while circle and line elements position the facial features with explicit coordinate values.
