This example demonstrates the mechanics of loading and parsing CSV data by displaying a brief summary of the CSS Named Colors dataset, including its size in kilobytes, row count, and column count. The visualization relies on D3 v5’s `d3.csv` method to fetch the remote file and parse it, while `d3.csvFormat` and the `.columns` property of the parsed data supply the statistics. The code also includes commented alternatives using `fetch` with `async`/`await` and a "pyramid of doom" pattern, highlighting different approaches to asynchronous data loading.
