{"version":"1.0","type":"rich","title":"S'Army","description":"S'Army draws an unclassed and classed proportional-symbol map of simulated COVID-19 infection counts across North America, using `d3.geoPath` with a stereographic projection for the base map and `d3.scaleSqrt` for proportional symbol sizing. Circles are placed at the centroids of Canadian census divisions and U.S. counties, with populations from the 2016 Canadian Census and the 2019 U.S. Census Bureau estimates. The visualization uses `d3.scaleThreshold` for a classed legend copied from the Johns Hopkins map, and readers can toggle between provinces/census divisions, states/counties, and proportional/classed scaling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/55ff40ccd6314ced8d40ba741db176a5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
