This example draws a bright yellow cartoon face using SVG shapes, with two eyes, a mouth, and animated eyebrows. The face is centered within an SVG canvas using D3 selections and transformation attributes. Eyebrows animate up and down using chained `transition().duration()` calls. The code utilizes `d3.select`, `d3.arc` for the mouth path, and D3’s transition system to create the motion. The rendering approach is purely declarative SVG construction in a React-free environment, with styles defined in a separate CSS file.
