{"version":"1.0","type":"rich","title":"Fork of Simulated COVID maps in the US and Canada","description":"This example shows simulated COVID-19 case counts across US counties and Canadian census divisions, with boundaries switchable to states and provinces and circle scaling switchable between proportional and classed modes. It uses d3.geoStereographic for projection, d3.geoPath for SVG paths, and d3.scaleThreshold or d3.scaleSqrt for circle radii. Data comes from 2019 US county and 2016 Canadian census population estimates, with populations divided by 100 to create fake infection rates. The classed legend and color scheme follow the Johns Hopkins COVID map.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/302395c192f44128afa36bae2189a710?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
