This example constructs a stylized face using D3.js and SVG primitives. It draws yellow circles for the head and eyes, black rectangles for eyebrows, and a path for a mouth created with the `d3.arc` helper. The right eyebrow animates vertically, thanks to chained `transition` calls on the `attr` property. The visualization loads D3 from a CDN and uses `select` and `append` to build the SVG hierarchy, with `translate` centering elements on a 960 by 500 canvas.
