{"version":"1.0","type":"rich","title":"life-expectancy-map","description":"This interactive choropleth map displays global life expectancy by country, with a selectable year slider that updates the color-coded visualization. Built with React and D3 v7, it loads UN WPP data from a CSV file and combines it with world GeoJSON topology using continent geometry from world-atlas. The map uses d3.geoPath, d3.scaleSequential, and d3.interpolateYlGnBu to render country polygons, while d3.pointer and mouse events drive tooltip interactions showing country names and values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/573d1f71878c489eb3fe75b1bae8eac3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
