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.
