This example demonstrates how to load and display CSV data using React state management alongside D3 utilities. The application fetches a CSV file containing CSS named colors from a GitHub gist, then calculates and presents summary statistics including file size, row count, and column count. The code uses React’s `useState` and `useEffect` hooks to manage the asynchronous data loading via `d3.csv`, while the `d3.csvFormat` method in `message.js` computes the data’s size in kilobytes. The rendered output appears as large monospace text.
