This choropleth map visualizes global COVID-19 cumulative case counts by country, with each nation shaded according to its reported total. The map uses a natural Earth projection and is rendered as SVG, with a zoom interaction allowing users to inspect regions in detail. Data comes from a CSV file joined with world country boundaries from the World Atlas TopoJSON, while colors are assigned via d3.scaleOrdinal with a spectral scheme. Hovering reveals the country name and case count through an SVG title element.
