Fork of Choropleth (Topojson)
This fork of a choropleth map visualizes confirmed COVID-19 cases by department in Argentina, using a logarithmic color scale from pale yellow to deep purple, with a gradient legend and a hover tooltip displaying the department, province, and case count. It employs D3 v5, including `d3.geoPath` and a transverse Mercator projection via `d3-geo-projection`, to render TopoJSON data from a GitHub repository. The map includes interactive zoom (via `zoom` event) and a custom axis for the logarithmic scale.
