This example renders a smiling face as a React component using SVG, with d3.arc to draw the mouth path. The face is centered within a 1000x500 viewport, featuring a pink circle for the head, two red eyes positioned with fixed offsets, and a blue arc mouth. The code imports React and ReactDOM, uses d3.v7, and applies inline styling to remove page margins. The rendering approach manually defines SVG circle and path elements within a translated group.
