This example shows a smiling face rendered as an SVG graphic, featuring a yellow circular head with black outlined eyes and a curved mouth, overlaid with a gray stubble pattern on the lower face. The code uses React to define the SVG elements and D3’s `arc` generator to create the mouth path. A `pattern` defines the stubble dots, while a `clipPath` and `mask` restrict the stubble to the beard region, with all shapes positioned using absolute coordinates.
