{"version":"1.0","type":"rich","title":"Refactored Bar Chart","description":"This visualization presents a horizontal bar chart displaying the populations of ten countries from a UN dataset loaded via `d3.csv`. React state management with `useState` and `useEffect` handles asynchronous data loading, while D3 scales (`scaleBand` and `scaleLinear`) map country names and population values to SVG coordinates. The chart is rendered as SVG elements through reusable React components for axes and marks, with axis ticks generated directly from D3 scale methods.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/91771e72e7f645abbc34cf11afb23d02?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
