{"version":"1.0","type":"rich","title":"Fetching data","description":"This example displays basic metadata about a fetched CSV file, showing its size in kilobytes, row count, and column count in large text. It loads a named CSS colors dataset from a GitHub gist using the `d3.csv` method with a Promise-based `.then()` callback, then counts rows via `txt.length` and columns through `txt.columns.length`. The text size is computed from `d3.csvFormat(txt).length`. The page uses D3 v7 and renders the resulting information inside a `<pre>` element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/36f91301d39f407b873d6730f842c6dc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
