{"version":"1.0","type":"rich","title":"Bar Chart","description":"This example visualizes the top 10 most populous countries from the United Nations 2019 population dataset using a simple bar chart. Each country appears as a horizontal bar sized by its 2020 population estimate, rendered as SVG rectangles. The app loads the CSV data with `d3.csv`, scales the values using `scaleLinear` and `scaleBand`, and builds the bars through React components. The implementation uses React hooks like `useState` and `useEffect` to manage asynchronous data loading, with bars positioned vertically and extending horizontally according to population counts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d32ccc20214f43358aa51a894e18dbcc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
