A yellow smiley face with moving eyebrows demonstrates fundamental DOM manipulation using D3.js. The visualization is created with SVG elements, including circles for the face and eyes, rectangles for eyebrows, and a path for the mouth. D3 selections and the `arc` generator construct the face, while chained `transition` calls with `.duration(2000)` animate the eyebrows up and down. The source code is provided as an HTML file with a bundled JavaScript module.
