This example displays the size and structure of a CSS Named Colors CSV dataset by rendering a multi-line message with the file size, row count, and column count. The visualization uses D3 v5’s `d3.csv` to load and parse the remote CSV file, then formats the result with `d3.csvFormat` to compute the kilobyte size. The code also contains commented-out alternatives using `fetch`, `async`/`await`, and `d3.csvParse`, showing different methods for handling asynchronous data loading within a React framework.
