This example demonstrates how to load and parse a CSV file using D3, displaying the file’s size in kilobytes, row count, and column count. The code uses `d3.csv` to fetch a remote CSV of CSS named colors and returns an array of objects, then calculates metrics via `d3.csvFormat` and the resulting data’s properties. A commented alternative shows fetching the raw text with `fetch` and `response.text`, followed by `d3.csvParse`. The output appears in a large-font `<pre>` element.
