Cars Report
This example renders a blank SVG canvas with a red background using D3 v5 and a minimal HTML page. It selects the `<svg>` element with `d3.select`, then applies the background color via `style('background-color', 'red')`. The visualization does not yet display any data, serving as a starting point for adding car-related charts or reports. The code relies on the D3 library loaded from a CDN and demonstrates basic DOM selection and styling through D3’s API.
