A choropleth map colors countries by economic classification using an ordinal color scale applied via `d3.scaleOrdinal` and `d3.schemeSpectral`. The map renders with `d3.geoPath` and a Natural Earth projection, drawing country boundaries from TopoJSON data loaded from the World Atlas. Hovering highlights a country in red, and a custom color legend built with reusable D3 code shows the category colors. The visualization supports zoom and pan through `d3.zoom`, with all elements rendered as SVG.

Choropleth Map

A choropleth map colors countries by their economic classification using an ordinal color scale with the `schemeSpectral` palette. The visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to render world geography, with data loaded from the World Atlas TopoJSON and TSV files via `d3.json` and `d3.tsv`. A custom color legend displays the scale, and zooming is enabled through `d3.zoom`. Hovering highlights a country by turning it red.

Choropleth Map

This choropleth map colors countries by economic classification using an ordinal color scale with a spectral scheme. Hovering highlights a country in red, and the map includes a legend showing color categories. Built with D3 v5, it uses `geoPath` with the Natural Earth projection and loads geographic data from the world-atlas TopoJSON and TSV files. The visualization supports zooming via D3's zoom event and renders as an SVG.

Choropleth Map

This choropleth map visualizes countries colored by their economic classification, using a spectral color scale to distinguish categories. The map renders geographic boundaries as SVG paths via `d3.geoPath` and a Natural Earth projection. Data is loaded from the World Atlas TopoJSON and TSV files, merged by country ID, then assigned to the `d3.scaleOrdinal` color scale. A custom legend shows color swatches with labels, and hovering highlights individual countries in red. Interaction includes zoom and pan through the `d3.zoom` event, which applies an SVG transform.

Choropleth Map

This choropleth map colors countries by economic classification using an ordinal color scale derived from `d3.scaleOrdinal` and `schemeSpectral`. The map renders with `d3.geoNaturalEarth1` projection and `d3.geoPath`, while country geometries and names come from TopoJSON and TSV data loaded via `Promise.all`. A semi-transparent legend built from `d3.scaleOrdinal` domains shows color categories, and `d3.zoom` enables panning and zooming over the SVG. Hovering highlights individual countries in red.

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

This choropleth map colors countries by their economic classification using a categorical ordinal color scale from `d3.scaleOrdinal` with the `schemeSpectral` palette. It renders world geography with `d3.geoPath` and a Natural Earth projection, loading TopoJSON country boundaries and TSV metadata from the world-atlas package. A custom color legend built with D3 selections appears alongside the map, while `d3.zoom` enables panning and zooming. The visualization uses SVG elements and includes hover effects that highlight individual countries.

Choropleth Map

This choropleth map colors countries by economic classification using an ordinal color scale with a spectral palette. The visualization includes a custom SVG color legend showing category colors and labels. Built with D3 v5, it uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering, and applies zoom interactions. The map loads TopoJSON data from world-atlas and joins it with TSV metadata to assign country properties. Hovering highlights individual countries in red.

Choropleth Map

A choropleth map colors countries by economic classification, with an ordinal color scale and a legend showing each category. Built with D3 v5, it uses `geoNaturalEarth1` and `geoPath` for the projection, `topojson` to load world geometry from the world-atlas dataset, and `schemeSpectral` for the color range. The map supports zooming via `d3.zoom`, while hover effects highlight individual countries.
