This example demonstrates how to load and parse CSV data using D3 v7, displaying a summary of the dataset’s size in rows, columns, and kilobytes. It fetches a remote CSV file of named CSS colors via `d3.csv`, then computes the row count from the parsed array and column count from `data.columns`. The page’s message is updated with this information, showing the result in large text. The code also includes commented alternatives using the Fetch API with `async/await`.
