This example demonstrates a minimal D3 starter template: it renders the text “Hello D3 version 7” in the center of the page at a font size of 13em. The page loads D3 v7 from a CDN and uses the `select` method from the D3 API to target the body element and set its text content via `.text()`. The code shows a basic setup with an HTML file and a separate JavaScript bundle, which is the standard starting point for building D3 visualizations.
