This example renders a cartoon face in SVG using D3.js, with a yellow circular head, two eyes, and eyebrows that animate upward and back down. The code constructs the face by appending circles and rectangles to a group centered on the canvas, then uses `transition().duration()` to create a brief eyebrow-raising motion. A mouth is drawn with D3’s `arc()` generator, specifying inner and outer radii and angular range. The scene is static except for the eyebrow animation, demonstrating basic SVG shape construction and tweened transitions within a React framework.
