This example shows a web page titled “Timeline” that displays the text “Hello HTML” in large, centered type, alongside a “Hello JavaScript!” message logged to the browser’s console. The page loads D3 v5 and Moment.js from CDNs, but the code does not yet implement any visualization or timeline functionality. It uses plain CSS for styling and JavaScript for console output, serving as a minimal scaffold for future data-driven timeline work. The React starter project is referenced as a related alternative.
