{"version":"1.0","type":"rich","title":"Activity6_Q4","description":"This interactive bubble chart visualizes the relationship between GDP, life expectancy, and population for ten countries. The x-axis represents GDP in trillions of USD, the y-axis shows life expectancy in years, and the circle size encodes population using a square-root scale. Each bubble is colored according to a categorical variable from the CSV data. The visualization is built with D3.js v6, using `d3.scaleLinear` for the axes, `d3.scaleSqrt` for bubble sizes, and SVG rendering with axes labeled directly.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/79ffc284a9e246a5bda4794caa4e2bde?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
