This example demonstrates fundamental DOM manipulation with D3.js by constructing a yellow smiley face from SVG shapes, including two eyes, movable eyebrows, and an arc-based mouth. The face is centered within an 960×500 SVG canvas, with all elements grouped and positioned using D3’s `select`, `append`, and `attr` methods. The code uses D3’s `arc` generator to draw the mouth and manually sets coordinates for circles and rectangles to form the eyes and eyebrows. Static SVG rendering emphasizes programmatic shape creation rather than data binding or interaction.
