This example shows a React component that asynchronously loads a CSV file of CSS named colors and displays a message summarizing the loaded data. The visualization uses `useState` to manage the loading state, and calls `d3.csv` to fetch and parse the data from a remote URL. Once loaded, the message reports the approximate file size in kilobytes, the number of rows, and the number of columns. The interface is rendered with React DOM, using a large monospaced `<pre>` element for the text output.
