This example shows a simple SVG face created using D3.js. The visualization begins with an empty SVG element that is programmatically selected and styled with a red background via `d3.select`. The code demonstrates the foundational use of D3 version 6 for DOM manipulation and basic SVG rendering within a React framework. The data source is minimal, relying on hard-coded styling rather than loaded datasets, and the rendering approach uses the SVG namespace provided by the HTML document.
