This example demonstrates how to load and summarize a CSV dataset of CSS named colors using D3 utilities within a React application. It displays a text message showing the data’s size in kilobytes, row count, and column count once the file is fetched via the `d3.csv` method, with React’s `useState` and `useEffect` hooks managing the asynchronous data loading and state updates. The visualization renders as plain SVG text in a `<pre>` element.
