{"version":"1.0","type":"rich","title":"Loading data","description":"A loading screen displays the message “Rendering data with react” in large type until a CSV file of CSS named colors is fetched. Once loaded, the app maps each row to a horizontal div strip, using the color’s RGB hex value as its background. The example demonstrates asynchronous CSV loading via `d3.csv` and state-driven rendering with React’s `useState` and `useEffect`, producing a stacked color swatch visualization in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c0712a3888cd401b965dbf62b308d2af?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
