This example demonstrates the minimal setup required to render text with D3 version 7, displaying “Hello D3 version 7” centered in the browser window. The page loads D3 from a CDN and uses the `select` method to target the `body` element, then applies the text via the `.text()` API. The markup includes a 13em font size for visibility, and the code relies on a bundled JavaScript file for execution. It serves as a basic template for initializing D3 projects.
