{"version":"1.0","type":"rich","title":"Kepler Exoplanet Search Results","description":"This example displays basic file metadata from the NASA Kepler Exoplanet Search Results dataset, showing the CSV’s size in kilobytes, row count, and column count in large text. It uses the `d3.csv` method to load and parse the remote CSV file from a GitHub gist, then accesses the parsed data’s `length` and `columns` properties. The code also includes commented alternatives using `fetch` with `async`/`await` and a nested promise “pyramid of doom,” illustrating different asynchronous loading patterns with D3 v5.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f7ac1863aec04536bf9751bd638b10c4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
