This example demonstrates a React-based HTML starter page that displays the text “Hello HTML” in large, centered typography. It integrates D3.js to load a CSV file from `data.csv` using the `csv` function, logging the parsed data to the browser console. The page also includes basic CSS styling for body alignment and font size, while JavaScript logs a separate “Hello JavaScript!” message. The visualization focuses on minimal HTML/CSS/JavaScript integration, with D3 handling data loading from an external source.
