A static yellow smiley face rendered as SVG, with two dark eye circles and a mouth arc positioned half-way toward the final shape. The outer face uses a filled yellow circle with a black stroke, while the mouth is drawn using D3's `arc` generator with inner and outer radii, spanning from π/2 to π radians. The code selects the SVG element with `d3.select` and appends a group translated to the center, relying on D3 v7 to construct the arc path. Eye positions and sizes are hardcoded, and no data source is involved.
