This example displays a minimal “Hello D3” message centered on the page using the D3 library. The code imports the `select` function from D3 and calls `select('body').text('Hello D3')` to set the text content of the body element. The page is styled with a large font size and top margin via inline CSS, and the script is loaded from a bundled `bundle.js` file. The project depends on D3 version 6.7.0 and is configured for VizHub.
