This example demonstrates a minimal D3 setup by displaying the text “zkn dckn dskcn m D3 version 7” centered on a blank page using D3 v7. It shows how to select the body element with `d3.select` and set its text content, while the HTML file loads the D3 library from unpkg and includes a separate `bundle.js` script. The styling is applied via a CSS rule for large font size and centered alignment. The code relies on the `select` API from D3 and the standard DOM manipulation methods.
