A yellow smiley face with animated eyebrows is drawn entirely in SVG using D3.js v5. The code demonstrates fundamental DOM manipulation by selecting the SVG element, appending groups, and building the face from basic shapes like circles and rectangles. D3 transitions move a shared eyebrow group up and down over two one-second intervals, while a mouth path is created using the `d3.arc` generator with specified inner and outer radii and smile angles.
