This example demonstrates a bare-bones D3.js setup within an HTML page, featuring a large centered message that displays the result of logging the D3 library object to the browser console. The page uses a CSS class to style the text at a 13-em font size and imports D3 version 7 via a CDN script tag. The code explicitly calls `console.log(d3)` inside a div element, showing how the library is loaded and made accessible for further interactive visualizations.
