This example demonstrates a React component that loads a CSS named color dataset from a GitHub gist using d3.csv and displays a summary of the file size, row count, and column count. The code uses React's useState and useEffect hooks to manage the asynchronous data loading, while the Message.js utility formats the statistics using d3.csvFormat. The rendered output shows a large-text loading message that transitions to the data summary once the CSV is fetched, with error-prone duplicate D3 script includes in the HTML. The visualization is purely textual, using ReactDOM to render a `<pre>` element with the file's metadata.
