This example draws a stylized yellow face in SVG using D3.js, with circles for eyes, rectangles for eyebrows, and an arc-generated path for the mouth. The eyebrows animate upward and back down via chained `transition().duration()` calls on a group element. All shapes are positioned relative to a centered `<g>` container, using D3 selections and the `arc()` generator from the d3-shape module to construct the mouth.
