This example uses D3.js v7 to demonstrate how to draw a simple face directly onto an SVG canvas. The code selects the SVG element and applies a red background color via the `d3.select` and `style` methods. It loads D3 from UNPKG and imports from local ES6 modules, showcasing basic SVG rendering without any data or interactive features. The result is a static, minimal illustration of D3’s selection and styling capabilities.
