{"version":"1.0","type":"rich","title":"Fork of Circle on the Map3","description":"This visualization displays population projections for countries on a natural Earth map, with animated circles representing data values that transition across years (2030–2040) from a CSV dataset. It uses D3 v5 with `geoNaturalEarth1` and `geoPath` to render country boundaries, while `scaleSqrt` sizes the circles based on population values. The map supports zooming via `d3.zoom`, and a color legend and size legend accompany the chart. Data is loaded from CSV and TopoJSON files, with circles animating their radius and position over time.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/34a8119dc6d04b9dbd7c3e433b465838?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
