This example demonstrates how to load and parse CSV data, reporting the file size, row count, and column count of the CSS Named Colors dataset. It uses D3 v5's `d3.csv` method to fetch the remote CSV file, then applies `d3.csvFormat` to calculate the data size in kilobytes. A commented-out alternative shows the same workflow using the Fetch API with async/await and `d3.csvParse`, highlighting different approaches to asynchronous data loading in a React-less HTML page.
