A yellow smiley face is drawn on a dark background using SVG shapes, with animated eyebrows that rise and fall over two seconds. The example demonstrates fundamental D3.js v3 DOM manipulation by building the face with `circle` elements, a `rect` for each eyebrow, and a `path` created with the `d3.arc` helper for the mouth. The eyebrows are moved using chained `transition().duration()` calls, which shift the group’s `transform` attribute to create the up-and-down motion. All shapes are centered within an SVG canvas using a translated `<g>` element.
