This example demonstrates how to load and parse external CSV data, displaying the file size, row count, and column count of the dataset. Using D3 v7, it fetches a CSV file containing CSS named colors via `d3.csv`, which parses the data into an array of objects. The resulting metrics are formatted and rendered as large text in an HTML page. Alternative implementations using `fetch` with `d3.csvParse` are shown in commented code, highlighting different approaches to the same task.
