This example demonstrates how to load external data in a React component using D3 utilities and display a text summary of the dataset. The application fetches a CSV file containing CSS named colors via `d3.csv`, stores the parsed result in React state with the `useState` and `useEffect` hooks, and shows a message with the file size in kilobytes, number of rows, and number of columns using a custom `message` function that relies on `d3.csvFormat`. The data is rendered as large text in an SVG-compatible HTML page.
