This example demonstrates loading CSS named color data from a remote CSV file using D3’s `csv` utility, with React’s `useState` and `useEffect` hooks managing the asynchronous fetch and component state. The resulting view renders a plain-text summary of the dataset size—calculating kilobytes, row count, and column count using `d3.csvFormat`—inside a large `<pre>` element. While the data loads, the React component displays a "Loading..." message. The visualization uses React 16.9, D3 v6, and relies on a gist-hosted CSV as its sole data source.
