This example shows a green background, a large yellow circle, and a simplified smiley face rendered as SVG. The face includes two circular eyes, rectangular eyebrows, and a mouth drawn as an arc using D3’s `arc` generator. The code imports `select` and `arc` from d3, appends SVG elements to a fixed 960×500 canvas, and positions them via transformations. The eyebrows are offset vertically, suggesting movement, but no animation or data is included—only static DOM manipulation.
