This example displays a header message taken from a JSON dataset, rendering the text “aaaa” in large type at the top of the page. It loads data from a static structure defined in `totos.js`, which exports an array of objects parsed with `JSON.parse`. The React application uses `index.js` to import the data and directly update the DOM via `document.getElementById('mess').textContent`, while the accompanying `index.html` provides the root container and a pre-formatted message area. The visualization itself is minimal, showcasing a single textual value without any charts or interactive elements.
