This example displays the text “Hello HTML” centered on a white page, with the body’s font size set to a very large 13em. It serves as a minimal demonstration of basic HTML and CSS styling, alongside a JavaScript `console.log` statement that outputs “Hello JavaScript!” to the browser’s developer console. The page uses plain HTML elements, a `<style>` block for CSS, and an inline `<script>` for JavaScript. It does not incorporate any data visualization or external libraries, serving purely as a starting point for static web content.
