This example displays basic statistics about a CSS colors dataset, including its size in kilobytes, row count, and column count, rendered as large text. It loads the data asynchronously from a GitHub gist using `d3.csv`, then computes the file size with `d3.csvFormat` and `Math.round`. The page uses D3 v7 and a plain HTML preamble, with the results injected into a `<pre>` element. The visualization focuses on summarizing the dataset’s dimensions rather than plotting points or shapes.
