This example displays a single, large-format “Hello D3 version 7” message in the center of the page using D3’s `select` and `.text` methods. The rendering relies on the D3 v7 library loaded from a CDN, with all styling handled by inline CSS. The page contains no interactive elements or data sources, serving purely as a minimal starter template that demonstrates how to bind text to the body element and update it via D3’s selection API. The bundle.js file is the entry point that runs the static text insertion.
