{"version":"1.0","type":"rich","title":"Activity6_Question4","description":"This D3.js v7 bubble chart visualizes the relationship between GDP per capita, life expectancy, and population for countries in 2007, with bubbles positioned by GDP (on a log scale) and life expectancy, while bubble size encodes population. The chart uses `d3.scaleLog`, `d3.scaleSqrt`, and `d3.scaleOrdinal` to map data attributes, and renders in SVG with hover tooltips built via `d3.select` and the `.join` operator. Data is loaded from a CSV file containing country-level indicators, and the visualization includes legends for bubble size and continent color coding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f1aad5ff09b841ccbd3b7d22cf03f005?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
