This example shows a rabbit-like smiley face built with D3.js, featuring a yellow circular head, eyes, buck teeth, and raised eyebrows. The code demonstrates fundamental DOM manipulation by appending SVG shapes and applying chained transitions that animate the eyebrows upward and change their fill to red, then return them to their original position and color. It uses D3 v5 selections and the `arc` generator for the mouth, with a static SVG canvas and no external data source.
