Make a Face
This example renders a blank red SVG canvas with an empty `<svg>` element sized 960 by 500 pixels. It demonstrates how to set up a basic D3.js v5 project using `d3.select` to modify the background color of the SVG. The page includes a linked stylesheet that removes default margins and hides overflow, ensuring the visualization fills the viewport. The code serves as a minimal starting point for building SVG-based data visualizations, though it does not yet draw any shapes or data.
