This example uses D3.js v5 to construct a static smiley face from SVG primitives. It draws a yellow circle for the head, two smaller circles for eyes, rectangular eyebrows, and a path-based mouth arc. The visualization demonstrates fundamental DOM manipulation by appending and positioning graphical elements with methods like `select`, `append`, and `attr` on an SVG canvas. The eyebrows are positioned but do not animate in the provided code.
