This visualization shows a smiley face composed of a yellow circle with black outline, two eye circles, and a mouth arc, all centered in an SVG canvas. Built with React and D3 v5, it renders statically using SVG elements. The code imports D3’s `arc()` API to generate the mouth path, while React DOM manages the SVG structure. The face is positioned via a translation transform on a group, with fixed dimensions and coordinates defining each facial feature.
