This example renders a stylized face using D3.js v5 within a React framework, displayed as scalable vector graphics with animated eyebrows. A yellow circle forms the head, with two smaller circles for eyes and a path-based arc for the mouth. The code uses D3’s `select` and `append` to build the SVG structure, `arc()` to generate the mouth path, and chained `.transition().duration()` calls to animate the eyebrow rectangles vertically over two seconds each, creating a subtle bobbing motion. The animation runs in an HTML page that loads D3 from a CDN.
