This example demonstrates a minimal D3.js visualization that renders an empty SVG canvas with a solid red background. The code imports the `select` function from D3 and uses it to target an SVG element within an HTML page, then applies the background color styling through D3’s `style` method. The visualization relies on D3 v7.6.1, loaded via the unpkg CDN, and the complete setup is contained in an `index.html` file with a separate `bundle.js` script for the custom logic.
