{"version":"1.0","type":"rich","title":"The Wealth & Health of Nations","description":"This animated scatterplot charts the relationship between income per capita and life expectancy for nations from 1800 onward, using log and linear scales on the x- and y-axes respectively. Each circle represents a country, with its position determined by economic and health metrics, its area encoding population, and its color indicating region. The visualization includes a year label, axes with descriptive labels, and interactive tooltips that display the country name and population on hover. Built with D3 v3, the chart loads time-series data from a JSON file and interpolates values for each year, animating the transition as the year label updates.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-dff1a7c6cc088b398cd4fd41a343d9c6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
