This visualization displays basic statistics about a CSS Named Colors CSV dataset, showing the file size in kilobytes, row count, and column count. The code uses d3.csv to load and parse the data from a GitHub gist, then calculates metrics from the parsed result. It also demonstrates alternative approaches using the Fetch API with async/await and d3.csvParse, though these are commented out. The output is rendered as large text in a pre element using vanilla JavaScript.
