Teal circles sized by confirmed cases and red circles for deaths appear over each country, with a date ticker and hover tooltips providing detail. Built with D3.js (v5), it uses `geoPath` and a Natural Earth projection, animating circle radii via `transition()`. Population data comes from a CSV file (`data01.csv`) and country shapes from the VisionsCarto World Atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5011a23c5c9b4525b5189aa79af6e25b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
