This example displays a large static message reading “Hello HTML!” centered on the page, styled with a 13em font size. It fetches JSON data from a GitHub repository using the Fetch API, but the retrieved records—showing first and last names—are appended as plain text divs into a container, with no visual mapping or charting. The visualization relies solely on JavaScript’s `fetch` and DOM manipulation via `document.createElement`, with basic CSS for layout. No charting library or data-binding framework is used despite the React label in the metadata.
