{"version":"1.0","type":"rich","title":"Activity6_Ques4","description":"This bubble chart visualizes the correlation between GDP per capita, life expectancy, and population area ratio across 20 countries. Each circle’s position encodes GDP per capita (x-axis) and life expectancy (y-axis), while its radius represents population density. The visualization uses D3 v7 with SVG rendering and interactive tooltips that display country-specific values on hover. A categorical color scale distinguishes countries, paired with a legend. The chart reads data from a CSV file and animates tooltip transitions, with circle opacity increasing on mouseover for enhanced readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ba367b8185ed453b8ffe26c70f75286d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
