This example demonstrates the process of loading and parsing CSV data using D3 v5 within a React framework. It fetches a CSS Named Colors dataset from a GitHub gist and displays basic statistics about the file, including its size in kilobytes, row count, and column count. The code uses the `d3.csv` method to asynchronously load and parse the data, then calculates metrics using `d3.csvFormat` and the data’s built-in `length` and `columns` properties. The results are rendered as text in a large `<pre>` element.
