This example draws a stylized face using SVG shapes in a 960x500 viewport. A yellow circle forms the head, with two smaller dark circles for eyes and an arc-based path creating a mouth, all positioned via absolute coordinates and a translated group. The code uses D3 v6 selection methods (`select`, `append`, `attr`) and the `d3.arc` generator to construct the mouth path with inner and outer radii and specified start/end angles. CSS rules define stroke styles for path elements, though the classes are not applied in the visible script. The rendering is entirely SVG, with D3 handling DOM manipulation.
