This example demonstrates the minimal setup required to render text with D3 version 7. It displays the phrase “Hello D3 version 7” in the center of the page at a large font size. The code imports the `select` function from `d3` and uses it to target the `body` element, setting its text content directly. The page loads D3 from a CDN and executes the custom script from a separate bundle file, showing a straightforward integration pattern.
