This example displays a static, full-screen HTML message reading “Hello HTML!” centered in the browser window. It uses a plain HTML structure with a linked stylesheet, where the `.message` class applies a 13-em font size and text alignment. The page loads a JavaScript module that only logs “hello world” to the console, with no interactive or dynamic visualization. The rendering relies solely on standard DOM elements and CSS styling, with no charting, data, or animation libraries included.
