{"version":"1.0","type":"rich","title":"Refactored Barchart","description":"This horizontal bar chart displays the population of ten countries from the UN Population 2019 dataset. React renders SVG elements, while D3’s `scaleBand` and `scaleLinear` position bars and axes. The `AxisBottom` and `AxisLeft` components generate ticks, and `Marks` maps data to rectangles with native `<title>` tooltips using `format(\".2s\")`. Population values are formatted as billions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f8454101db0a43efbb2cd50adcd3f0e8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
