A stylized yellow face rendered in SVG, built with React and D3 v7, features animated eyebrows and a frowning mouth. The code uses `d3.select`, `d3.arc`, and chained `.transition().duration()` calls to move eyebrow rectangles vertically over two seconds, while static circles form the eyes and a path from `arc()` creates the mouth. The face is centered using SVG `g` transforms, with all shapes drawn directly in an HTML page.
