{"version":"1.0","type":"rich","title":"Using arcs for rendering Data with React","description":"This example visualizes United Nations population data from a CSV file, loading the data with `d3.csv` into React state via the `useState` and `useEffect` hooks. It renders the dataset as a series of SVG rectangles whose height and width are mapped to population values, with a loading indicator shown until the data arrives. The code demonstrates integrating D3’s data-loading utilities with React’s component lifecycle and SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/51fd48e6a97a435eb4afdcd47b1177ab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
