This example demonstrates loading a CSV dataset in a React application and displaying a summary of its contents. The code uses React hooks (`useState`, `useEffect`) to fetch the data asynchronously with D3’s `csv` function, then renders a formatted message showing the file size in kilobytes, row count, and column count. The data source is a GitHub gist containing CSS named colors, rendered as SVG text in a `<pre>` element. The visualization relies on React 17, D3 v7, and the `d3.csvFormat` API for calculating the data size.
