{"version":"1.0","type":"rich","title":"Fork of Simulated COVID maps in the US and Canada","description":"This interactive map uses D3.js v5 to simulate COVID-19 case counts across the United States and Canada. It plots scaled circles on a stereographic projection, with population data for counties and census divisions from 2016/2019 sources. Users can toggle between proportional and classed circle scaling, and switch subdivision granularity between states/provinces and counties/census divisions. The visualization draws GeoJSON boundaries and centroids via d3.geoPath, with circle radii determined by either d3.scaleSqrt or d3.scaleThreshold.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5c731a2a8008431fab960cf6cbdda1ee?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
