This example displays the text “Hello D3 version 6” centered on a plain white page, using a large 13em font size. It serves as a minimal starter template for D3 v6, importing the `select` function from the D3 library to target the `<body>` element and set its text content. The page loads D3 v6 from the official CDN and runs the logic in a separate bundle, demonstrating a basic setup for building more complex visualizations. The accompanying video provides guidance on initializing a D3 project.
