{"version":"1.0","type":"rich","title":"activity 6_Task 1","description":"This bar chart displays the top 30 countries by population in 2020, using horizontal bars sorted by country name. Built with React and D3 v5, it uses `scaleBand` for the y-axis, `scaleLinear` for the x-axis, and SVG rendering for the marks. Data is loaded via `csv` from a GitHub-hosted dataset, with population values multiplied by 1000. The chart includes custom axis components and formats tick labels using D3's `format` with SI prefixes, converting \"G\" to \"B\" for billions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a58fdcc02a624228ac8d9ed6e764f680?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
