This example demonstrates a minimal D3.js version 7 starter project. It renders the text “Hello D3 version 7” centered in the browser window using the `select` API from D3 to target the HTML body element. The page loads D3 from an unpkg CDN link and applies CSS styling to set the font size to 13em. The visualization serves as a basic template for initializing D3 projects, relying on the `d3.select` function to manipulate the DOM directly.
