ICE4 by Sujit demonstrates fundamental DOM manipulation with D3.js through an interactive smiley face whose eyebrows animate. The page renders an SVG scene with multiple character faces, using D3 to select elements and update attributes in response to user interaction. The dark background contrasts with orange and brown face shapes, and the eyebrow motion is driven by simple data-bound updates. The example highlights D3’s core strength in handling dynamic DOM changes while maintaining a playful, lightweight visualization.
