This example demonstrates the minimal setup required to combine HTML, CSS, and JavaScript with D3.js, rendering a large “Hello HTML!” message centered on the page. The code loads D3 v7 from a CDN, imports the `select` function, and logs a string imported from a separate module. The rendering approach uses a simple HTML `<div>` styled via CSS, with no data visualization or interactive elements, focusing instead on the integration of ES modules and D3 in a plain HTML context.
