The example produces a stylized face as an SVG graphic using D3.js v5. It begins with a red background on the selected `svg` element, then constructs facial features through D3’s data-driven selection and path generation methods. The `styles.css` file defines classes for the face’s lines and stroke properties, while the JavaScript imports `select` from D3 to manipulate the DOM. The final face is drawn entirely with SVG elements, relying on D3’s core selection and shape utilities without external data sources.
