{"version":"1.0","type":"rich","title":"Activity6_Question4.9","description":"This example displays a bubble chart comparing GDP and average life expectancy across ten countries, with bubble size scaled to population and colors mapped to country-specific values. Built with D3 v6 and rendered as SVG, it uses `d3.csv` to load the dataset, `scaleLinear` and `scaleSqrt` for positioning and radius, and `d3.axisBottom`/`axisLeft` for axes. A custom legend lists each country with its corresponding color swatch, and labels identify the axes and chart title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8ca0fdb5cc50453986a2ccc993717c46?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
