This example demonstrates a minimal D3 version 6 setup, displaying the text “Hello D3 version 6” centered on a plain white page at a very large font size. It uses the `select` API from the d3 module to target the `body` element and set its text content directly. The page loads D3 from a CDN and runs a bundled JavaScript file, with all styling defined in an inline style block. No data or interactive behavior is present, serving solely as a starting point for development.
