This example demonstrates the minimal setup required to render text with D3 version 7. It shows a large, centered "Hello D3 version 7" message on a blank page, using the `select` function from the d3 library to target the document body. The code imports `select` from 'd3' and chains the `.text()` method to set the text content. The page loads D3 via a CDN script tag and includes the bundled JavaScript through `bundle.js`. The visualization emphasizes the simplicity of beginning with D3's DOM manipulation capabilities.
