This visualization demonstrates how to import and summarize a CSV dataset using D3. It loads the CSS named colors dataset from a GitHub gist via `d3.csv`, then displays the file size in kilobytes, row count, and column count in a large text format. The page uses D3 v6 and plain HTML, with the results rendered into a `<pre>` element. The example highlights the promise-based data loading pattern and formatting utilities like `d3.csvFormat`.
