This example displays metadata about a CSS named colors dataset loaded from a GitHub gist, showing the file size in kilobytes, row count, and column count in large monospaced text. It uses D3 v7's `d3.csv` to fetch and parse the remote CSV file, then formats the data with `d3.csvFormat` to calculate its byte length. The page also includes commented-out alternative code using the Fetch API, `async`/`await`, and `d3.csvParse` to achieve the same result.
