This example demonstrates how to load and parse CSV data using D3, displaying the resulting dataset’s size as a simple text summary. It fetches a remote CSV file of CSS named colors via the `d3.csv()` method, then uses `d3.csvFormat()` to calculate the formatted data size in kilobytes, alongside row and column counts. The output is rendered in a large `<pre>` element. The code also includes commented-out alternatives using `fetch()` and `d3.csvParse()`, highlighting the preferred D3 approach.
