This example displays a summary of a CSV file containing CSS named colors. It fetches the data from a remote gist URL, then computes and presents the file size in kilobytes, the row count, and the column count within an HTML `<pre>` element. The code uses the D3.js version 6 library, specifically the `d3.csv` and `d3.csvFormat` functions, to handle data loading and formatting. The visualization is a simple text-based report of the dataset's structure, rendered on a plain HTML page.
