This example draws a cartoon face using D3.js version 5 and SVG. It renders a yellow circular head with green hat and ears, featuring eyebrows, white eyes with brown pupils and highlights, black eyelashes, and a red tongue within a pale mouth. The face also includes a moustache (implied) and is centered via a translated group. The code uses D3 selections and shape methods like `append`, `attr`, and `arc` to compose the illustration, with hardcoded pixel coordinates for precise placement.
