This example demonstrates fundamental DOM manipulation with D3.js by constructing a static smiley face out of SVG elements, including eyes, pupils, eyebrows, a nose, ears, glasses, blush circles, a mouth, teeth, and a beard. The code uses d3.select to create and style each shape, d3.arc to generate the nose and mouth paths, and a data join with d3.selectAll to bind an array of numbers to rectangular teeth. The purple face, black features, and red glasses are rendered entirely in SVG, with fixed coordinates and transforms, showing how D3 can build complex graphics through direct attribute manipulation.
