This example demonstrates a minimal HTML page that pairs CSS styling with JavaScript to display a large, centered text message. It shows the foundational structure of a web-based visualization using plain HTML elements and a CSS class for typography. The code relies on the native HTML `div` element, CSS font-size and text-align properties, and no external libraries. The rendering approach is static, using the browser’s default text layout. It serves as a starting point for understanding how markup and styles combine before introducing frameworks like React or data-driven libraries such as D3.
