This example demonstrates loading and parsing a CSV dataset of U.S. National Park Trails, displaying basic file statistics: size in kilobytes, row count, and column count. It uses D3.js v5’s `d3.csv` method to fetch and parse the remote CSV file asynchronously, then formats the result with `d3.csvFormat` and calculates metadata. The code also includes commented alternatives using the Fetch API with `async`/`await` and a nested `fetch` callback approach, illustrating different parsing strategies. The visualization itself is purely text-based, rendered inside a large `<pre>` element.
