This example displays the text “Hello HTML” centered on a white background, serving as a minimal starting point for web-based visualizations. The page uses basic HTML and CSS styling within a single `index.html` file, with a large font size applied to the body. It references a `data.csv` file containing yearly running totals, but the current code does not load or render this data. The example demonstrates a bare-bones HTML structure that could be extended with JavaScript libraries for data visualization.
