This example displays a loading screen that reports the size, row count, and column count of a CSV dataset once it is fetched. The implementation uses React's `useState` hook within an `App` component, while the asynchronous data retrieval relies on D3’s `d3.csv` method, pulling from a remote gist containing CSS named colors. Upon completion, the `d3.csvFormat` API calculates the data’s byte size, and the result is rendered inside an HTML `<pre>` element.
