This example demonstrates how to retrieve and summarize a remote CSV file using D3.js. It fetches a comma-separated file containing CSS named colors from a GitHub gist, then displays a text summary of the data’s size in kilobytes, row count, and column count using `d3.csv()` and `d3.csvFormat()`. The result is rendered into an HTML `<pre>` element, with the asynchronous fetch handled via `fetch()` and JavaScript’s `async`/`await` pattern. The page uses the d3.v5 library and relies on basic DOM manipulation.
