{"version":"1.0","type":"rich","title":"Circle on the Map3","description":"This visualization animates population projections on a world map, displaying how the size of circles at country locations changes over time from 2020 onward. The map is rendered using D3 v5 with an SVG projection via `d3.geoNaturalEarth1` and `d3.geoPath`, while the circles use `d3.scaleSqrt` for sizing. A timestamped sequence of transitions animates the circles’ radii across years, driven by data from a CSV of population estimates. The map also supports zooming through D3’s `zoom` behavior, with hover tooltips highlighting country details.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c9641a604e9d4b88a2a4123ef621e059?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
