This example displays basic metadata about the US school ranking top 150 dataset, showing the file size in kilobytes, row count, and column count in large text. It loads a CSV file from a GitHub gist using `d3.csv` and formats the result with `d3.csvFormat` to calculate the byte size. The page also includes commented-out alternatives using the Fetch API with `async`/`await` and `d3.csvParse`, though the active version relies on D3 v5’s promise-based CSV loading.
