This interactive choropleth map visualizes world countries colored by economy type, using a Natural Earth projection rendered as SVG through `d3.geoPath` and `geoNaturalEarth1`. The map, populated with country boundaries from TopoJSON and attribute data from a TSV source, supports zooming via `d3.zoom` and displays detailed country information—including population, GDP, and continent—in a custom tooltip on hover. A clickable legend highlights countries matching each economy category, while country labels are placed with overlap detection to maintain readability.
