This example displays a simple red rectangular SVG canvas as a static visual. The code selects the SVG element using D3 v5 and applies a red background color through the `style` method. The project structure includes separate files for HTML, CSS, and JavaScript, with the main logic in `index.html` and a basic `console.log` in `index.js`. The visualization demonstrates basic D3 selection and styling without any data-driven elements or interactions.
