{"version":"1.0","type":"rich","title":"Bar Chart: Population of 20 countries in 2010","description":"A horizontal bar chart ranks the 20 most populous countries in 2010, with each bar’s length proportional to population. The chart uses D3 v7’s `scaleLinear` and `scaleBand` to map population values and country names to pixels. Data is loaded from a CSV via `d3.csv`, processed with `d3.autoType`, and sorted using `d3.descending`. Bars are rendered as SVG `<rect>` elements with a hover color change, and axes are drawn using `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c8f00b32ed654265acb6c27fb343b026?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
