This example demonstrates a minimal D3 v7 starter template that displays “Hello World” in large text on a webpage. It loads D3 from a CDN, defines a small array of car objects with properties like year, make, and price, and parses it into JSON using `JSON.parse`. The code then selects the `message-element` via `document.getElementById` and sets its text content to the message. The visualization is purely text-based, with no charts or interactive elements.
