This example demonstrates a static HTML message styled with CSS and a large font size, serving as a minimal starting point for a React and D3.js project. The page loads React 16.9, ReactDOM, and D3 v5 from a CDN, but the visible content is simply a centered “Hello HTML!” message. The code uses the `d3.csv` function imported from `d3` in a separate `getData.js` file, suggesting an intended data-loading pipeline, though no data is fetched or visualized in the rendered output. The styling and structure are defined in `index.html` with inline style rules.
