{"version":"1.0","type":"rich","title":"Activity 6_task 1 Q2","description":"This bar chart displays the top 20 countries by population in 2010, with countries listed alphabetically on the y-axis and population values on the x-axis. Built with React and D3 v5, the visualization uses `scaleBand` and `scaleLinear` to map the data, rendered as SVG rectangles. Population values are formatted using `format('.2s')` to display billions. Data is loaded from a CSV file using `d3.csv` in a custom `useData` hook, with hover effects changing bar colors and tooltips showing exact population values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8c39929d40c04d838f55bd800061e463?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
