A grid of eighteen procedurally generated smiley faces fills the SVG canvas. Each face is a distinct combination of randomly sized features: circular yellow heads with black strokes, pairs of eyes, rectangular noses, and arc-based mouths. The visualization is built with React components, using D3 v7’s `d3.arc()` API to create the curved mouth paths and `d3.range()` to generate the array of faces. All facial elements are positioned relative to a common center point, rendered as SVG within a React app.
