This example demonstrates how to load and summarize a CSV file from a remote URL using D3 v7. It fetches data containing CSS named colors and displays three metrics in a large text block: file size in kilobytes, row count, and column count. The code uses the `d3.csv` method to parse the data and `d3.csvFormat` to calculate its string length for size estimation. Results are inserted into the page via the DOM API `textContent`.
