A blue smiley face with black stroke outline, two eyes, and an upward curved mouth rendered as SVG. The face is centered on a 960 by 500 canvas. The visualization uses React components to define the SVG elements and D3’s `arc` generator to create the mouth path. The face, eyes, and mouth are positioned via a central `g` transform using D3’s coordinate calculations and React’s JSX syntax, with styling controlled by inline attributes.
