This example demonstrates a minimal SVG face-making exercise with a red background, showcasing the basic setup for a D3.js visualization within a React framework. The code selects an SVG element using `d3.select` and applies a CSS style directly to it. It includes an HTML file loading D3 v5 from a CDN and a separate stylesheet, providing a simple template for building custom visualizations. The visualization emphasizes foundational SVG manipulation and styling rather than complex data-driven graphics.
