This example demonstrates a minimal HTML page displaying the text "Hello HTML" in large, centered type, with basic CSS styling. It represents a simple baseline for web visualization projects, showing how a page can render static content without additional libraries. The code uses plain HTML elements, inline CSS, and a short JavaScript snippet that logs "Hello JavaScript!" to the browser’s developer console. This serves as a starting point for embedding more complex visualizations, such as those built with D3 or React.
