{"version":"1.0","type":"rich","title":"Activity6_Q1.2","description":"This bar chart displays the population of the top 20 countries in 2010, with the data loaded from a CSV file using D3’s `csv` function. The visualization uses React with reusable axis components (`AxisBottom`, `AxisLeft`) and a `Marks` component that renders SVG rectangles. D3’s `scaleBand` and `scaleLinear` position the bars, while `format` abbreviates tick labels from units like “G” to “B”. Hovering a bar reveals its exact value via a native SVG `<title>` tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8938093d0bbe4a04805d1465ff9085ac?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
