This example demonstrates how to load and parse CSV data using D3 v5 and the Fetch API. It displays a summary of the dataset’s size, row count, and column count in a large text block. The code uses `d3.csv` to fetch and parse the file, then `d3.csvFormat` to measure its size, and also includes commented-out alternatives using `fetch` with `async`/`await` and `d3.csvParse`. The data source is a CSV file containing CSS named colors.
