This example shows an interactive summary of the CSS Named Colors dataset, reporting the file size in kilobytes, the number of rows, and the number of columns. A large, preformatted text element displays the statistics prominently. The code loads the CSV using d3.csv, then derives the file size with `d3.csvFormat(data).length`, while also accessing the parsed data’s `length` and `columns` properties. The example additionally demonstrates an alternative approach using `fetch`, `async`, and `await` with `d3.csvParse`, though that path is commented out.
