This example demonstrates a minimal webpage that displays the text "Hello HTML" in the center of the browser window, styled with CSS to use a very large font size. The page is built with a simple HTML file and includes a small JavaScript script that logs "Hello JavaScript!" to the browser's developer console. This example uses the native HTML `script` element to execute JavaScript code, and the CSS `body` rule to control text alignment and font size, providing a starting point for web-based visualization projects.
