{"version":"1.0","type":"rich","title":"Fork of Covid19 world map","description":"This map visualizes cumulative COVID-19 cases per country as of June 6, 2021, using circle size to encode case counts over a natural Earth projection. Missing data appears in red, while countries with data are gray. The visualization loads spatial boundaries from TopoJSON and joins them with case counts from a CSV using `d3.csv` and `d3.json`. It employs `d3.geoPath` for map rendering, `d3.geoNaturalEarth1` for projection, and `d3.scaleSqrt` for proportional symbol sizing, with zoom via `d3.zoom` and interactive tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/85a631978c4943bb99f9e29503dc4659?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
