{"version":"1.0","type":"rich","title":"dv2020-ep21-viz20 - bar chart","description":"A horizontal bar chart displays the 20 most populous countries in 2020, ranked in descending order by population. The visualization uses React to render SVG rectangles, with D3's `scaleBand` and `scaleLinear` mapping country names to y-coordinates and population values to bar widths. Data comes from the UN World Population Prospects 2019, loaded via D3's `csv` parser and sorted with `d3.descending`. The chart updates dynamically as React re-renders when the asynchronous data fetch completes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1141f4e61d29451c8a847e0870285e9c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
