This example displays a text-based summary of a CSV dataset loaded from a GitHub gist, showing the file size in kilobytes, row count, and column count. The visualization uses React hooks to fetch and store the data with `d3.csv`, then displays the computed message. Built with React and D3 v6, the app renders the result as an SVG-rendered preformatted text element, with the `csvFormat` API calculating the data length and the `columns` property determining the column count.
