This example displays basic information about a CSV dataset in large text, showing the row count, column count, and file size in kilobytes. It loads CSS named colors from a GitHub-hosted CSV file using the `d3.csv` promise API, then formats the data with `d3.csvFormat` to calculate its byte length. The result is inserted into an HTML `<pre>` element via the DOM, demonstrating a minimal data-loading and metrics-display workflow with D3 v6 in a plain React-less environment.
