This visualization displays a cheerful yellow smiley face centered within an SVG canvas. The face’s eyebrows rise and fall in a repeated animation, creating a lively expression. The example demonstrates fundamental DOM manipulation with D3.js v5, using `select`, `append`, and attribute setters to construct circles, rectangles, and an arc-based mouth. Animation relies on chained `transition().duration()` calls to move the eyebrow group vertically. The code defines explicit pixel coordinates for facial features, and the rendering uses SVG elements within a fixed 960×500 viewport.
