{"version":"1.0","type":"rich","title":"Datavis 2020 Episode 16 - Loading Data in React","description":"This example demonstrates how to load external data in a React application using D3 utilities, displaying file size, row count, and column count asynchronously. The app uses React hooks (`useState`, `useEffect`) to manage loading state and fetch a CSV file of CSS named colors from a GitHub gist. Once loaded, the `d3.csv` function parses the data, and `d3.csvFormat` calculates the data size in kilobytes for display. The interface shows a large text message before and after loading, with React re-rendering the output once the data arrives.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d206ce64314245879cd3ebff21322337?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
