{"version":"1.0","type":"rich","title":"Population Bar Chart","description":"This chart displays the 20 most populous countries in 2020 as horizontal bars, with country names on the y-axis and population values scaled along the x-axis. Built with React and D3 v5, it uses `d3.scaleBand` and `d3.scaleLinear` for the axes and renders SVG rectangles. Population figures come from the United Nations’ 2019 World Population Prospects, formatted with d3’s `format` to show billions or millions. Native SVG `<title>` elements provide tooltips on each bar.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a09247a83e6d4384805b520d20a33dd4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
