This example demonstrates how D3.js can be used inside an HTML page, displaying a large "Hello HTML!" message that fills the screen. The page loads D3 version 7.8.0 from a CDN and runs a script that logs a string from an imported module (something.js) to the console. It also outputs the d3.scaleLinear function to verify D3’s availability. The rendering relies solely on standard HTML and CSS, with no visual data mapping or interactive elements shown.
