{"version":"1.0","type":"rich","title":"Refactored Bar Chart","description":"A horizontal bar chart displays population data for ten countries in 2020, loaded from a CSV file hosted on GitHub. The React app uses a custom hook with `d3.csv` to fetch and parse the data, storing it in state. SVG rendering builds the visualization from reusable components: `AxisBottom` creates the linear population scale, `AxisLeft` labels the categorical country bands, and `Marks` draws rectangles using `scaleBand` and `scaleLinear`. The chart updates upon data loading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3a8b554fd6e84c688790f0dcbb43b643?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
