This visualization shows a smiley face built with SVG primitives, featuring a yellow circle with a thick black outline, two offset eyes, and a curved mouth rendered as an arc. The example uses a React component structure, with the face, eyes, and mouth defined as nested SVG elements within a transformed group. D3 v7’s `arc` generator constructs the mouth path by specifying inner and outer radii and start and end angles, while ReactDOM renders the final composition into a root div.
