{"version":"1.0","type":"rich","title":"activity 6_Task 1","description":"This visualization displays the 2020 population estimates for 30 countries as a horizontal bar chart, with the x-axis formatted in billions using D3’s `format` function. The bars are rendered as SVG rectangles scaled by `scaleLinear` and `scaleBand`, while custom `AxisBottom` and `AxisLeft` components generate the tick marks and labels. The data is loaded from a CSV file via `d3.csv`, and hover tooltips show exact values through the native SVG `<title>` element. The chart is built with React and D3 v5, using `useState` and `useEffect` for data fetching.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bee1e6306d2b4f679ba6a5b9d58b6eda?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
