This example demonstrates how to load and display a CSV dataset using React state and D3 utilities. It fetches CSS named colors data from a GitHub gist via `d3.csv`, stores the parsed result in React’s `useState` hook, and renders a summary message showing the file size in kilobytes, column count, and row count using `d3.csvFormat`. The interface displays a large, monospace loading message until the data arrives, then updates dynamically. The code highlights the integration of D3’s asynchronous data loading with React’s component lifecycle and state management.
