This example demonstrates loading and parsing CSV data with D3 v7 in a React framework. It fetches a CSV file of CSS named colors from a GitHub gist and displays summary statistics—file size in kilobytes, row count, and column count—in a large text element. The code uses `d3.csv` for asynchronous loading and parsing, then `d3.csvFormat` to calculate byte length, and accesses `data.length` and `data.columns.length` for row and column totals. An alternative commented approach shows fetching text with the Fetch API and parsing via `d3.csvParse`.
