{"version":"1.0","type":"rich","title":"Loading and Parsing CSV Data on \"All Space Missions from 1957\"","description":"This example displays summary statistics for a CSV dataset of all space missions from 1957, showing the file size in kilobytes, row count, and column count in large text. It loads the data using `d3.csv` with a promise, then calculates the metrics via `d3.csvFormat` and the parsed data’s `length` and `columns` properties. The code also includes commented alternatives using `fetch` with `async/await` and `d3.csvParse`, as well as a nested promise “pyramid of doom” pattern. The data source is a raw GitHub Gist URL.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bb2b188b9dc24da7a07768f23c71cb80?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
