This example showcases a minimal HTML page that uses D3 version 6 to render the text "Hello D3 version 6" directly into the body. The page demonstrates basic integration of D3 with a static HTML structure, applying CSS for centered, large-font styling. The code imports the `select` function from D3 and uses it to set the text content of the body element. It relies on the D3 library loaded from a CDN and a bundled JavaScript file for execution.
