This example demonstrates how to load a CSV dataset of CSS named colors using D3 utilities and React state management. The application fetches the data from an external GitHub gist via the `d3.csv` function, then displays a concise summary showing file size in kilobytes, row count, and column count within a styled `<pre>` element. React's `useState` and `useEffect` hooks control the data loading lifecycle, initially rendering a "Loading..." message until the asynchronous request completes. The visualization highlights the integration of D3's data-fetching capabilities with React's component-based rendering and state handling.
