This example presents a classic smiley face built entirely from SVG shapes. The face, eyes, eyebrows, nose, mouth, cheeks, hair, and teeth are all created using D3.js selection and append methods, which add circles, lines, and paths to the SVG canvas. The styling is handled through a separate CSS file, using transform properties for positioning and rotation. The code demonstrates D3’s basic API for constructing static, styled visual elements with data-driven markup.
