Test
This example demonstrates how to initialize D3 version 7 by selecting the HTML body element and rendering the text “Hello D3 version 7” directly into the page. It uses the `d3.select` method from the core D3 library to target the DOM node and the `text` method to set its content. The code also includes a console log output for verification. The visualization is presented as a minimal, static text output, with the page’s styling centered and enlarged via CSS. The rendering relies on JavaScript executing within the HTML document, loading D3 from a remote package source.
