This example demonstrates how D3's data-loading utilities can be integrated with React’s state management. It fetches a CSV file of CSS named colors from a GitHub gist using D3’s `csv` function, then displays a summary message in a React component. The message, generated by a custom module, reports the data’s formatted size in kilobytes, row count, and column count. The visualization is rendered as SVG through React, using D3 v5 and React 16.9, with the output displayed as plain text inside a `<pre>` element.
