This example demonstrates the minimal setup required to begin using D3 version 7, displaying the text “Helloo D3 version 6” in the center of the page with a font size of 13em. The code loads D3 from a CDN and uses the `select` function to target the body element, then calls the `.text()` method to inject content. It relies on `bundle.js`, which imports `select` from the `d3` module, showcasing a modern ES module approach. The example serves as a bare-bones starting point for D3 projects, highlighting the core selection and DOM manipulation API.
