{"version":"1.0","type":"rich","title":"GapMinder (CP341 Style)","description":"A dual-panel visualization shows global health and economic trends from 1800 to 2014, with a scatter plot of GDP per capita against average lifespan and a line chart tracking lifespan over time. Animated transitions update both panels as a slider or keyboard controls change the year. Tooltips reveal population details, while historical annotations like the Spanish Flu appear contextually. The implementation uses d3.v6 with `scaleLog`, `scaleLinear`, data joins, and SVG transitions, processing raw country data into Maps keyed by year.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ddaf97dd93f04e6d95f373fb9eb64bd5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
