{"version":"1.0","type":"rich","title":"Fetching CSV","description":"This example shows how to load and parse three CSV files in parallel, then displays the sum of their `number` fields in a large heading. It uses the Fetch API and Promises to request the files, and d3-dsv’s `d3_dsv.csvParse` to convert each response text into an array of objects. After all three fetches complete via `Promise.all`, the code reads the first row’s `number` value from each parsed dataset, adds them together, and updates the page’s result span. The data sources are three local CSV files, each containing a single numeric value.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-42477281de0005e40088fc872f5826aa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
