{"version":"1.0","type":"rich","title":"Fork of Circles on a Map","description":"A world map visualization displays each country's 2018 population using semitransparent circles scaled by the square root of population, with a size legend and a color legend showing population ranges. Users can pan and zoom the map by applying d3.zoom, and hovering over a country reveals its exact population via a tooltip from a title element. The map is rendered with d3.geoNaturalEarth1 and d3.geoPath using TopoJSON data from the visionscarto-world-atlas, while population values are sourced from an Our World in Data CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1b6b893947c94e58ac0cf7fa0c7090bc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
