This example displays metadata about a CSS Named Colors dataset loaded from a CSV file, showing the file size in kilobytes, row count, and column count as plain text. Using D3 v5 and React, the code demonstrates two equivalent approaches: `d3.csv` with promises, and the Fetch API combined with `async`/`await` and `d3.csvParse`. The rendering updates a `<pre>` element’s text content, highlighting different methods for asynchronous data loading and parsing.
