This example demonstrates how to load and parse CSV data using D3.js, displaying summary statistics about the dataset directly on the page. It fetches a CSV file containing CSS named colors from a GitHub gist and calculates the file size in kilobytes, row count, and column count. The visualization uses `d3.csv` to asynchronously retrieve and parse the data, then `d3.csvFormat` to measure its length, and finally updates a `<pre>` element with the results. No charts or graphics are rendered—only the textual metadata is shown.
