{"version":"1.0","type":"rich","title":"learning loading of data","description":"This example demonstrates how to load and summarize a remote CSV dataset using D3.js v7. It fetches a CSV file from a GitHub gist, parses it with `d3.csvParse`, and displays the file size, row count, and column count alongside a dynamically generated HTML table of the data. A loading spinner animation is shown until the fetch completes, with error handling if the request fails. The page uses a green background and styled cards to present the dataset summary and preview clearly.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a04e5398e56f48d5825b68aadaed372d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
