This example demonstrates the process of loading and parsing CSV data, displaying the dataset’s size in kilobytes, row count, and column count in a large, readable format. It uses D3 v7’s `d3.csv` and `d3.csvFormat` to fetch and measure a CSV file of CSS named colors from a GitHub repository. The code also includes commented alternatives using the Fetch API, `async`/`await`, and `d3.csvParse`, as well as a nested promise “pyramid of doom” pattern, contrasting different async data-loading techniques.
