This example demonstrates how to load and parse CSV data using D3.js version 5. It fetches a remote CSV file containing CSS named colors, then displays summary statistics about the dataset, including its size in kilobytes, row count, and column count. The visualization uses the `d3.csv` function to asynchronously retrieve and parse the data, `d3.csvFormat` to measure the data’s serialized size, and the `data.columns` property to count columns. Results are rendered as plain text inside an HTML `<pre>` element, showcasing D3’s data-handling capabilities without any graphical chart.
