A simple D3.js face built from basic SVG shapes—a yellow circle for the head, two eyes, animated eyebrows, and an arc-based mouth—is centered on a blank canvas. The eyebrows continuously move up and down using chained `transition()` calls over two seconds each. The visualization demonstrates fundamental D3 v5 concepts, including `select` for DOM access, `attr` for positioning, and the `arc` generator to create the mouth path, with all elements drawn as SVG primitives.
