{"version":"1.0","type":"rich","title":"Esperance / Natalité : World","description":"This animated scatterplot charts global life expectancy against fertility rates from 1950 to 2015, with each country represented as a circle whose size encodes population and whose color indicates continent. The visualization, built with D3 v4 and rendered as SVG, plays through time with a sliding year indicator, allowing viewers to observe how the relationship between these two demographic indicators evolves across the world. Data is drawn from a CSV containing country, year, life expectancy, total fertility, population, and continent for each annual observation.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-e94a9f849d71659d8cbe57fb4d9c5c7b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"yes\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
