Madan's ICE-4 displays a stylized smiley face constructed from layered SVG shapes, including circles, ellipses, lines, and an arc-based mouth. The face features colorful eyes, a purple nose, black facial hair lines, and blue arms with yellow hands, all centered within a yellow head outlined in red. The visualization is built using React for component rendering and D3 v7’s `arc()` API to generate the mouth path, with all elements positioned using explicit coordinates within an SVG canvas.
