This example renders a placeholder message instead of a chart, with a 13-em font-size text centered on the page. The React app fetches a CSV of pizza sales data from a GitHub gist using the `fetch` API, but the response is not processed or displayed. The code imports React and ReactDOM, defines an `App` component that makes the fetch call, and mounts it to the `#root` element using `ReactDOM.render`. No visualization is implemented; the example demonstrates only the initial data-fetching setup.
