This example demonstrates loading a CSV dataset from a remote URL using D3 v5 and managing the resulting data with React state. The application fetches a list of CSS named colors and displays a text summary showing the file size in kilobytes, row count, and column count. The code uses the `csv` function from D3, the `useState` and `useEffect` hooks from React, and dynamically renders the message using the `message` helper function. While the data loads, a "Loading..." message appears.
