{"version":"1.0","type":"rich","title":"Bar chart","description":"This bar chart displays the top 10 countries by 2020 population from a UN Population dataset loaded via `d3.csv`. It uses React with hooks (`useState`, `useEffect`) to fetch and store the data, then renders SVG rectangles scaled by `d3.scaleBand` for countries and `d3.scaleLinear` for population values. Gridlines and axis ticks are generated with `xScale.ticks()`, and the chart is drawn within a margin-based layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9670f3e9eaaf4f59a46b5ade69b312f9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
