This example demonstrates the asynchronous loading and parsing of a CSV file containing CSS named colors. It displays the file size in kilobytes, the number of data rows, and the number of columns. The implementation uses d3.v5's `d3.csv` method to fetch and parse the remote data, then formats the summary with `d3.csvFormat`. An alternative commented-out approach uses native `fetch`, `async`/`await`, and `d3.csvParse` to achieve the same result, highlighting different methods for handling data in a React-based visualization.
