{"version":"1.0","type":"rich","title":"Circles on a Map","description":"This map visualization depicts world population by country, with circle area scaled to the 2020 population figures. Users can pan and zoom across the interactive SVG, and hovering over a country highlights it while revealing a tooltip with the region name and population. The visualization is built with d3.v5, using geoNaturalEarth1, geoPath, and geoCentroid for the map projection, while loadAndProcessData merges CSV population data with TopoJSON world atlas shapes. A square-root scale controls circle size, and custom legends render the data encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9e9d7b6f861548509b86e7408713583c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
