This example displays a simple text message, “Hi there,” in a large font on a blank page. It imports a small array of car objects from a separate module and uses plain DOM manipulation to set the text content of a pre element, rather than creating any charts or visualizations. The code relies on d3.v5 loaded via CDN, though no D3 methods are actually called. A CSS-fixed container is defined but left unused, and the message is derived from a hardcoded string, not from the imported car data.
