This example demonstrates the absolute minimum structure for a web page, displaying the static text "Hello HTML" centered in the browser. The page is defined entirely within a single `index.html` file, containing a `<style>` block that sets the font size and alignment, and a `<script>` block that logs the message "Hello JavaScript!" to the console. The example serves as a baseline starting point, showing no data or visualization, and is intended to be expanded upon with additional HTML, CSS, and JavaScript.
