A smiling face is drawn with SVG shapes, with a yellow circle for the head, two eyes, and a mouth formed using the d3.arc path generator. The animated eyebrows, rendered as rectangles, repeatedly transition upward and back down over two-second intervals using D3's transition method. The example demonstrates fundamental DOM selection and manipulation through d3.select, attribute setting, and chained transitions, operating entirely within a 960×500 SVG canvas.
