{"version":"1.0","type":"rich","title":"bar chart with React & D3r","description":"A bar chart displays the top 10 countries by 2020 population, with horizontal bars sized by population values from a UN Population 2019 CSV. The React app uses `useState` and `useEffect` to asynchronously fetch the data via D3’s `csv` loader, then renders SVG rectangles scaled by `scaleBand` for countries on the y-axis and `scaleLinear` for population on the x-axis. D3 v7 and React 16.9 are loaded from CDNs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1d15c8b5c40643198ead750c4d034f85?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
