This example demonstrates how to load and parse CSV data using D3 v5, displaying summary statistics about the CSS Named Colors dataset. The page shows file size in kilobytes, row count, and column count in large text. The primary implementation uses `d3.csv` with a promise callback, while commented-out alternatives illustrate `fetch` with async/await and `d3.csvParse`, as well as a nested promise pattern, to compare different data-loading approaches.
