Eight identical stylized faces are arranged in a grid, each rendered as a yellow circle with black-outlined eyes and a smile formed by a d3.arc path. The React application maps over a d3.range to generate multiple Face components, each composed of SVG primitives within a FaceContainer. The example demonstrates modular component reuse, nested SVG grouping, and the use of D3’s arc generator for the mouth, all within a React-for-SVG workflow.
