This example builds a stylized face from basic SVG shapes—a yellow circle for the head, two eyes, animated eyebrows, and an arc-based mouth—centered within an SVG canvas. The code uses D3.js v5 selections and the `arc` generator to construct the mouth path, while `transition()` animates the eyebrows in a looping up-and-down motion. React serves as the hosting framework, and rendering relies on SVG elements with D3’s declarative attribute chaining.
