This example demonstrates how to load and parse CSV data using the D3.js library. It displays the file size in kilobytes, row count, and column count of a remote CSV file containing CSS named colors after fetching it with `d3.csv`. The asynchronous operation retrieves data from a GitHub Gist URL, then uses `d3.csvFormat` to measure the data size and presents the summary in a large HTML `<pre>` element.
