This example shows a yellow smiley face composed of a background circle, two eyes, and a mouth, rendered as scalable vector graphics within a web page. The visualization is built using React components, with each facial feature defined as a JSX element, and relies on D3’s `arc` generator to produce the curved mouth path. The drawing coordinates are calculated from the SVG’s fixed width and height, and the face is positioned at the center using a transformation group. The code demonstrates mixing React’s declarative UI with D3’s geometry utilities to create a static, geometric illustration.
