{"version":"1.0","type":"rich","title":"Loading and Parsing CSV Data","description":"This example demonstrates loading and parsing CSV data using D3.js, displaying the data size in kilobytes, row count, and column count in a large text element. It uses the `d3.csv` method to fetch and parse the CSV file from a GitHub gist, then accesses the parsed data array and its `columns` property to calculate the metrics. The code also includes commented alternatives using `fetch` with `d3.csvParse` and a nested promise pyramid approach, though the active path runs the external DaData API POST request instead.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ccd6462c1fa64ab989fbaf18abcb8a21?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
