This choropleth map displays confirmed COVID-19 cases across Argentine departments, using a logarithmic color scale from blue to red to represent case counts. The visualization loads GeoJSON data from a GitHub repository and renders department boundaries as SVG paths via `d3.geoPath` with a `geoTransverseMercator` projection. It employs `d3.scaleLog` for color mapping and includes interactive zooming through `d3.zoom`. Hovering over a department highlights it in pink and reveals a tooltip with the department name, province, and case count.
