{"version":"1.0","type":"rich","title":"Testing around with Chloropleth","description":"This visualization combines a choropleth map with a scatter plot to explore global demographic data. A world map displays countries colored by birth rate, while the adjacent scatter plot shows fertility rate against life expectancy, with population mapped to circle size. The map and scatter plot are linked: hovering over a country in either view highlights the corresponding element in the other. Built with React and D3 v6, the map uses `d3.geoEqualEarth` projection with `d3.geoPath`, while both views rely on `d3.scaleLinear` and `d3.scaleOrdinal` for color and size encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/16a99e26969b4f36b623eb4d9de4925b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
