{"version":"1.0","type":"rich","title":"Assignment6_Question4.9","description":"This bubble chart compares GDP and average life expectancy across ten countries, with circle size encoding population and color identifying each nation. The visualization uses D3.js v6 scales (`d3.scaleLinear`, `d3.scaleSqrt`) and SVG rendering to position bubbles, draw axes with `d3.axisBottom` and `d3.axisLeft`, and generate a custom legend. Data is loaded from a local CSV file via `d3.csv`, with labels for axes and a title providing context.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4edd249afbca4729b3e8782a78411f11?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
