This example demonstrates the fundamental structure of a web page that uses D3 and custom styling, displaying a large “Hello HTML!” message in Roboto font. The code shows how to load a CSV file containing x and y coordinates asynchronously using a Promise wrapper around `d3.csv`, then iterates over the loaded data rows with `forEach` to log each object to the console. The page includes external D3 v7 and d3-fetch libraries via CDN, plus Google Fonts for typography. It highlights basic data-fetching patterns without any visual charting yet.
