A stylized smiley face rendered as a reusable React component, composed of geometric SVG shapes for the head, eyes, nose, mouth, and mustache. The face is drawn with a white background circle, black outline, green nose, red mustache, and a curved black mouth arc. It uses React components like `BackgroundCircle`, `Eyes`, and `Mouth`, with the latter leveraging d3’s `arc` generator to create the smile path. All shapes are positioned relative to a central point via an SVG `<g>` transform, with no data source involved.
