A smiley face drawn with SVG shapes sits centered in a browser viewport. The code renders a yellow circular head with grey and black eyes, eyebrows, ears, and a grey mouth using React and D3’s `arc` generator for the curved paths. The visualization uses D3 v7 geometry functions for the mouth and ear arcs, while circles and ellipses are created as direct SVG elements. The static illustration demonstrates combining React components with D3-generated path data.
