{"version":"1.0","type":"rich","title":"Hierarchy Tree","description":"This interactive visualization combines a geographic map of countries with a scatter plot of global development indicators. The left panel uses a `d3.geoEqualEarth` projection with `d3.geoPath` to render country polygons, colored blue-white by birth rate. The right panel plots fertility rate against life expectancy using `d3.scaleLinear` for axes and point scaling, with circle size encoding population. Hovering highlights matching regions across both panels via `d3.selectAll` selectors. Data comes from world GEOJSON, world-data-2023.csv, and country-by-continent JSON sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4fc5eb554608462392314cf8dc74ef9e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
