This example shows a stylized smiley face rendered as a yellow circle with two eyes and a mouth, drawn using React’s JSX syntax inside an SVG container. The code uses D3’s `arc` generator from the `d3-shape` package to build the mouth path, while static SVG `<circle>` and `<path>` elements define the face. A single `<g>` group with a `transform` attribute centers the entire composition. The data source is hard-coded geometry values, and rendering uses ReactDOM with `d3.v7` to produce the final SVG output.
