This example summarizes and previews a CSV file fetched from a remote GitHub URL. It displays the file size in kilobytes, row count, and column count inside an interactive card, then renders the first five rows in an HTML table. The visualization uses D3 v7’s `d3.csvParse` to parse the downloaded text and D3 selections to dynamically build the table header and body cells. The data is loaded using the Fetch API, with a fallback error message if the request fails. The page relies on CSS styling with hover effects and card scaling for presentation.
