This example renders a plain HTML page with centered text, displaying “Hello” in a `<pre>` block and “Hello HTML” in the body. The styling uses a large font size of 13em, though the page does not include any data visualization. The code relies on basic HTML and CSS, with a minimal JavaScript file defining a `message` variable that is not used in the output. The page is a static, non-interactive starter template without external libraries like D3 or React.
