This example demonstrates a minimal D3 v7 starter template that renders the text “Hello D3 version 7” in the center of the page at a very large font size. The code imports the `select` and `arc` functions directly from the D3 library, logging the latter to the console before setting the body’s text content. The page loads D3 v7 from a CDN and uses a simple CSS style to center and scale the text, showing the basic setup for building D3-based visualizations.
