This example demonstrates how to load and summarize a CSV dataset using React state and D3 utilities. The app fetches CSS named colors from a GitHub gist via `d3.csv`, stores the parsed result in React’s `useState` hook, and displays its size, row count, and column count using `d3.csvFormat`. While loading, it renders a simple “Loading…” message. The visualization relies on React’s `useEffect` for the asynchronous data fetch and ReactDOM to mount the component, with D3 v6 providing the CSV parsing.
