This example demonstrates how to load and parse a CSV file using D3.js. It fetches a dataset of CSS named colors from a GitHub gist with `d3.csv`, then formats the raw data back to CSV using `d3.csvFormat` to calculate file size. The page displays the approximate data size in kilobytes, the number of rows, and the number of columns in a large `<pre>` element. The visualization focuses on summarizing dataset structure rather than plotting points or shapes.
