This example demonstrates a minimal "Hello D3 version 7" message rendered directly into a paragraph element using the `select` API from D3 v7. The page loads the D3 library from a CDN and applies a large 13em font size to the body for visual impact. The code imports the `select` function and calls it on the DOM to set the text content, showing how to begin using D3’s selection and manipulation methods in a straightforward way.
