A choropleth map colors countries by their economic classification using an ordinal color scale with a spectral scheme. The visualization loads world geometry from TopoJSON and country metadata from TSV, joining them by ISO numeric codes, and renders with D3’s `geoNaturalEarth1` projection and `geoPath`. A custom `colorLegend` displays the scale, while zooming and panning are enabled via `d3.zoom`. Hovering highlights countries, and tooltips reveal name and economy class.

Choropleth Map

A choropleth map colors countries by their economic classification, with a color legend showing ordinal categories from the Spectral scheme. The visualization loads world geometry from TopoJSON and joins it with tabular data from a TSV file. Using d3.geoPath with a geoNaturalEarth1 projection, it renders SVG paths that support zooming via d3.zoom. Hovering highlights individual countries, while a custom colorLegend component displays the color scale with circles and text labels.

Choropleth Map

This choropleth map colors countries by economic classification using a categorical ordinal scale with the Spectral scheme. It loads world geometry from TopoJSON and joins it with TSV metadata, then renders the map with d3.geoPath and a Natural Earth projection. The visualization includes an interactive color legend built with custom SVG components, and supports zooming and panning through d3.zoom. Hovering highlights individual countries in red, and tooltips display each country’s name and economic group.

Choropleth Map

A choropleth map colors countries by economic category using an ordinal color scale with a spectral palette. The visualization loads world geometry and country metadata from the world-atlas TopoJSON and TSV files, rendering paths with `d3.geoPath` and a Natural Earth projection. Users can pan and zoom via `d3.zoom`, while a custom legend built with D3 selections displays color categories as circles and text. Hovering highlights a country in red, and tooltips show each nation's name and economy type.

Choropleth Map

A choropleth map colors countries by economic classification using an ordinal color scale derived from d3.schemeSpectral. The visualization applies the d3.geoNaturalEarth1 projection and renders GeoJSON paths via d3.geoPath, with topology loaded from a world-atlas TopoJSON file and country names merged from a TSV lookup. Hovering highlights individual countries in coral, and d3.zoom enables interactive panning and scaling. A custom color legend displays the seven economy categories with labeled circles.
