This visualization displays total COVID-19 cases by country as of August 30, 2020, using red circles sized with d3.scaleSqrt and positioned via d3.geoCentroid and d3.geoNaturalEarth1 projection. The map employs d3.geoPath for country outlines and includes interactive zoom via d3.zoom. A color legend and size legend are rendered as SVG components using React, with data loaded from a CSV time series and TopoJSON world atlas. Hovering reveals country names and case counts through SVG title elements.
