A yellow face with two eyes and an open mouth is rendered inside an SVG. The face is built from reusable React components split across multiple ES6 modules, including separate files for the background circle, eyes, and mouth. The mouth shape is generated with the `d3.arc` API, while React's `<React.Fragment>` is used to group the eyes. All coordinates are hardcoded relative to the center of the 960×500 SVG canvas. The example demonstrates how to organize React components into modular files and use D3 utilities within a React rendering pipeline.
