A gray circle with a yellow outline serves as the face, featuring two small, colored eyes (red and blue) positioned symmetrically above the center. A separate arc path below creates a frown, representing a sad expression. The visualization uses React with D3’s `arc` generator to compute the mouth path, drawing it with an SVG `<path>` element. The face, eyes, and mouth are rendered as SVG shapes within a React component, using D3’s arc API for the curved mouth geometry.
