This example demonstrates the simplest possible D3 setup, rendering the literal text “Hello D3 version 6” centered on a blank white page at a very large font size. It uses the D3 v6 library, specifically the `select` method from the `d3` module, to target the empty `body` element and set its text content. The page loads D3 from the official CDN and runs the JavaScript logic from a separate bundle file, with no external data source or interactive behavior involved.
