This visualization displays the global distribution of total COVID-19 cases as of August 30, 2020, using proportional red circles overlaid on a natural Earth projection map. The map is rendered with SVG, using d3.geoPath for country outlines and d3.geoCentroid to position each circular marker. Circle radii are scaled with d3.scaleSqrt, while a color legend uses d3.scaleOrdinal with a spectral scheme to categorize data. Interactive zooming is enabled through the d3.zoom module, and data is loaded from a CSV file and TopoJSON world atlas using d3.csv and topojson.feature.
