This example displays the size and structure of a CSS Named Colors dataset, showing the file size in kilobytes, the number of rows, and the number of columns. The visualization uses D3.js v5, specifically the `d3.csv` method to load the CSV file and the `d3.csvFormat` function to measure the data length. The text is rendered in a large, fixed-size font within an HTML `<pre>` element, updating the message container dynamically once the data is parsed. The data source is a remote GitHub gist containing the named colors.
