A choropleth map colors world countries by their economy category using a spectral ordinal color scale, with an interactive color legend rendered as circles and labels. The visualization loads country geometries from TopoJSON and joins them with tabular metadata via a promise-based data pipeline. Rendered as SVG, it uses `d3.geoPath` with a Natural Earth projection and supports zooming through `d3.zoom`. Hovering highlights countries, while the legend is built using the exported `colorLegend` helper, with styling defined in external CSS.

Choropleth Map

This choropleth map colors world countries by their economy category using an ordinal color scale with a spectral scheme, and displays a color legend with clickable circles. It renders geographic boundaries with antialiased SVG paths via `d3.geoPath` and the Natural Earth projection, while loading data from the world-atlas package (TSV metadata and TopoJSON geometries) and processing it with `topojson.feature`. Hovering highlights a country in red, and the map supports zooming through the `d3.zoom` interaction.

Choropleth Map

A choropleth map colors countries by their economy category using an ordinal color scale with the spectral scheme, with hover highlighting and zooming via d3.zoom. It renders geographic paths with d3.geoPath and a Natural Earth projection, loading TopoJSON world-atlas data merged with TSV metadata. A custom color legend, built with SVG circles and text, displays the categorical scale.

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 of world countries colors each nation by its economy category using an ordinal spectral color scale. Data from the world-atlas TopoJSON and TSV files is projected with the Natural Earth projection and rendered as SVG paths. Hovering highlights a country, and a custom color legend with circles and labels is generated using the `colorLegend.js` module. The map supports interactive zooming via the `d3.zoom` API, which applies transformations to the map group on zoom events.

Choropleth Map

A choropleth map colors each country according to its economy category, using an ordinal color scale with a spectral scheme. The visualization loads world geography from TopoJSON and country metadata from TSV, then renders the map as SVG paths with a natural Earth projection. Hovering highlights a country in red, and a custom color legend displays the category colors. The map supports zooming and panning through d3.zoom, with d3.geoPath generating the geographic shapes.

Choropleth Map

This choropleth map colors countries by their economy category using a sequential spectral color scale. It renders world geography as SVG paths via the `d3.geoPath` and `d3.geoNaturalEarth1` projection, with zoom support through `d3.zoom`. Country names and values appear as tooltips, and a custom `colorLegend` component displays the ordinal scale. The data is loaded from a TopoJSON world atlas and a TSV mapping country IDs to metadata. Hovering highlights countries in red.

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

A choropleth map colors countries by their economy category using an ordinal color scale derived from the World Atlas TopoJSON dataset, which is joined with tab-separated metadata. The visualization uses d3.geoPath with a Natural Earth projection and supports zooming via d3.zoom. A custom color legend, built with SVG circles and text, displays the color scale categories. Countries are interactive, showing their name and economy group in a tooltip on hover, with a red highlight effect.
