A minimal starter template displays the static text "Hello D3" centered on a plain white page. The sample demonstrates the basic project structure for a D3 v7 application using an HTML file with an import map and a JavaScript module. It imports the `select` function from the D3 library to query the document body and apply the text content. The example focuses on the simplest possible setup for running D3 code, with styling handled by CSS to center the text and set an oversized font size.
