A smiling face emoticon is drawn as an SVG graphic, centered on a yellow circle with black outlines, white eyes, and a simple mouth. The visualization uses React to render static SVG elements directly in the DOM, with the face constructed from basic geometric shapes: circles for the head, eyes, and mouth. The styling is minimal, relying on inline SVG attributes and CSS for layout, and the data source is implicit in the hand-coded markup rather than fetched externally.
