This example demonstrates a minimal D3 starter page that renders the text “Hello D3 version 7” in the center of the browser window at a very large font size. It uses the D3 v7 library, specifically the `select` function from the `d3` module, to target the `body` element and set its text content. The page loads D3 from the unpkg CDN and runs the logic in a separate bundle.js file, with styling applied through a CSS rule that sets the body’s text alignment and font size.
