This example draws a simple emoticon face using SVG shapes rendered with D3 v6. It shows a yellow circle for the head, two black-outlined eyes, and a mouth created with the `d3.arc()` generator using specified inner and outer radii and angular ranges. The code selects the SVG element, parses its width and height attributes, and positions shapes relative to the center using numeric offsets. The face is constructed entirely with static, hard-coded dimensions and no external data source.
