{"version":"1.0","type":"rich","title":"Fork of Circles on a Map","description":"This example visualizes population by country using circles overlaid on a world map, with the area of each circle proportional to the country's 2018 population. The map uses a natural Earth projection, and users can pan and zoom the view. Hovering over a country reveals a tooltip with the country name and population. A size legend and color legend help interpret the circles, and countries with missing data appear in a distinct color. The visualization uses D3 v5 and renders in SVG, with zoom and hover interactions for exploration.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a05d9d103332434893a4ad831ebfc051?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
