This example demonstrates loading CSS named color data using React state and D3 utilities. The app displays a simple text summary showing the data size in kilobytes, row count, and column count, with a loading message before data arrives. It uses React’s `useState` hook to store the parsed CSV data and D3’s `csv` function to fetch and parse the remote dataset from a GitHub gist. The rendered output is a large `<pre>` element styled with a 5em font size, showing the computed metrics dynamically.
