A minimal D3 starter demonstrates the simplest possible D3 v7 setup: selecting a body element and setting its text to a greeting. The example uses the `d3.select` API from the imported `d3` module within an `index.js` file, while the HTML page loads the full library from a CDN and applies a large font size via CSS. The visible result is a single centered message, with the code revealing the core pattern of chaining a selection to a text assignment. No data source or complex rendering is involved, making it a clean baseline for learning D3's fundamental selection syntax.
