Fork of Choropleth Map
This fork of a choropleth map colors world countries by their economy category, using a spectral ordinal scale and a custom circle-based color legend. It renders geographic boundaries with `d3.geoPath` and a Natural Earth projection, and supports pan and zoom via `d3.zoom`. Data is loaded from the World Atlas TopoJSON and TSV files, processed with `topojson.feature`, and displayed as SVG paths with hover highlighting.
