{"version":"1.0","type":"rich","title":"Loading and Parsing CSV Data National Park Trails","description":"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.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5f44ed35751245d3b39ea12e0c183639?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
