Forked from Choropleth Map

This choropleth map colors world countries by their economic classification using a categorical color scale derived from d3.scaleOrdinal and d3.schemeSpectral. It draws geographic boundaries with d3.geoPath and a natural Earth projection, with hover highlighting and zooming via d3.zoom. Country metadata—including economy and income group—comes from a TSV file joined to TopoJSON geometry, and a custom legend component renders the color domain as circles with labels.

Choropleth Map

This choropleth map colors countries by economic classification using an ordinal color scale derived from d3.scaleOrdinal and d3.schemeSpectral. The visualization renders geographic boundaries with d3.geoPath and a natural Earth projection, with zooming enabled via d3.zoom. Hover effects highlight individual countries, and a custom color legend built with SVG circles and text explains the color categories. Country names and economic data are loaded from TopoJSON and TSV files using d3.json and d3.tsv.

Choropleth Map

A choropleth map colors world countries by their economy classification using an ordinal color scale with a diverging spectral scheme. The visualization includes a color legend and supports zooming and panning via d3.zoom. Geographic shapes are rendered with d3.geoPath and a natural Earth projection, using TopoJSON data from world-atlas and TSV metadata from the same source. Country names and economy values appear as tooltips.

Choropleth Map

This choropleth map colors countries by their economy classification using a categorical color scale derived from d3.scaleOrdinal and d3.schemeSpectral. It loads GeoJSON from TopoJSON world-atlas data and merges it with TSV metadata, then renders paths via d3.geoPath with a Natural Earth projection. Hovering highlights countries in red, while a custom color legend built with reusable D3 code displays the ordinal categories. Zoom and pan are enabled through d3.zoom, and the SVG output includes tooltips showing country names and economy values.

Choropleth Map

A choropleth map colors world countries by their economy classification, using a categorical ordinal color scale. The visualization loads geographic data from the world-atlas TopoJSON and TSV files, then renders the map via d3.geoPath with a natural Earth projection. Zooming is enabled through d3.zoom, and countries highlight red on hover. A custom color legend displays the economy categories as colored circles, while the map also shows a blue sphere background. The code uses d3.scaleOrdinal with schemeSpectral ranges to assign colors.

Choropleth Map

This choropleth map colors countries by their economy classification using an ordinal color scale derived from d3.scaleOrdinal and d3.schemeSpectral. It renders world geography with d3.geoPath and a Natural Earth projection, with zoom and pan via d3.zoom. A color legend built from d3.zoom and custom SVG circles and text displays the categorical levels. The data comes from a GitHub-hosted CSV joined to TopoJSON world atlas geometries using topojson.feature. Hovering highlights individual countries with a red fill.

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 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.
