A fork of a previous smiley face example, this React and D3 visualization renders a yellow SVG face with black stroke, two eyes, and a mouth defined by an arc path. The code uses React 16.9.0 for component structure and the `arc()` generator from D3 v5 to create the mouth shape, with all elements grouped and transformed to the center of a 960 by 500 viewport. The face is built from three circle elements and one path, with no external data source; dimensions and offsets are hardcoded constants.
