Forked from 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.

Choropleth Map

A choropleth map colors countries by their economy classification using an ordinal color scale with a spectral scheme. The visualization loads geographic data from the World Atlas TopoJSON and TSV files, projecting it with d3.geoNaturalEarth1 and rendering paths via d3.geoPath. Hovering highlights a country in red, while a custom color legend component displays the categorical ranges. Zooming is enabled through d3.zoom, and the map includes a static sphere background.

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 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 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 world choropleth map colors each country by its economy category using an ordinal color scale. The visualization uses d3 geoNaturalEarth1 projection with d3.geoPath to render countries from TopoJSON data, enriched with world-atlas TSV metadata. A custom color legend component displays the categories, and d3.zoom enables interactive panning and zooming. Country outlines appear in black, with hover effects highlighting individual nations in red.

Choropleth Map

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.
