{"version":"1.0","type":"rich","title":"Question4","description":"This scatterplot compares countries by GDP per capita (x-axis) and Life Ladder score (y-axis), using the World Happiness Report dataset. Each circle encodes social support through its radius and healthy life expectancy through a blue sequential color scale (d3.scaleSequential). The chart renders as SVG, with axes via d3.axisBottom and d3.axisLeft, plus hover interactions that enlarge points. A gradient legend displays the color mapping, while tooltips (title elements) reveal detailed country-year values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3edce585b68c4a0c8f8e43f5409f7cdf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
