Smiley Face Part 1
A yellow smiley face rendered with SVG sits centered on a dark background, featuring two black eyes and a curved mouth arc. Built with React and D3 v7, the visualization uses D3's `arc` generator to construct the mouth path, while circles define the face and eyes. The code imports `arc` directly from the d3 package and applies it within a React component that renders SVG elements, positioning everything via a translated group at the canvas center.
