{"version":"1.0","type":"rich","title":"Activity 7","description":"This visualization displays the top 20 countries by population in 2020 using a horizontal bar chart, rendered as SVG elements within a React application. The chart uses D3's `scaleBand` and `scaleLinear` to map country names and population values to visual positions, with a red-tinted axis and green bars. Population data is loaded via D3's `csv` function from a remote URL, and tooltips show formatted values using D3's `format` API. The chart includes custom axis components that label values with a \"B\" suffix for billions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f270ca1983804c91828151e472d71e76?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
