This example shows a minimal D3.js starter template that renders the text "Hello D3 version 7" centered on a plain white page. The visualization is generated using the `d3.select` method to target the body element and the `.text()` method to set its content. The code uses the D3 library version 7.6.1, loaded via a CDN, and relies on an external `bundle.js` file for the JavaScript logic. The page styling is defined with an inline CSS rule that sets a very large font size of 13em for the body.
