This example builds a silver smiley face in SVG using D3.js v5, with a yellow stroke and animated eyebrows that move up and down over two-second transitions. The code selects the SVG element, appends a group centered on the canvas, and constructs facial features including circles for eyes, rectangles for eyebrows, and a path generated with `d3.arc` for the mouth. The eyebrows transition their vertical position using chained `transition.attr` calls, demonstrating fundamental DOM manipulation and animation with D3’s selection and transition APIs.
