This example displays the text "Hello" in the browser, centered with a very large font size, alongside a minimal HTML document structure. It serves as a bare-bones template for starting a visualization, using the native HTML5 `<!DOCTYPE html>` declaration, a `<style>` tag for CSS styling, and a `<script>` tag that outputs "Hello JavaScript" to the console. No external libraries are loaded. The page is rendered directly by the browser, and the data is static, defined entirely within the HTML and CSS.
