Using D3.js v5, this example builds a simple cartoon face from SVG shapes: a yellow circle head, two dark eyes, rectangular eyebrows, and an arc-based smile. The code employs D3 selections to append elements and `d3.arc` to generate the mouth path. Animated eyebrows move via chained `transition().duration()` calls, shifting vertically and returning, creating a blinking-like effect. The rendering uses SVG with a centered group transform, and all visual components are defined programmatically with fixed numeric constants for spacing and size.
