This example draws a cartoon face using D3.js v5, rendered as an SVG with a yellow circular head, eyes, eyebrows, and a mouth created using the `d3.arc` path generator. The page also includes an animated left eyebrow that moves down and back up via chained `transition().duration(2000)` calls, while the right eyebrow remains static. All shapes are positioned with explicit pixel coordinates within a 960x500 SVG canvas.
