This interactive choropleth map displays world countries colored by economic classification, with a legend that filters the map by clicking a category. Users can zoom and pan the map, and selected countries are highlighted while unselected ones fade. The visualization uses D3 v5 APIs including `d3.geoNaturalEarth1`, `d3.geoPath`, `d3.zoom`, and `d3.scaleOrdinal`, rendering with SVG. Data comes from the World Atlas TopoJSON file merged with TSV metadata.

Choropleth Map with Interactive Filtering

This choropleth map displays world countries colored by economic classification, with an interactive color legend that filters the map when clicked. Hovering reveals country names and values via tooltips, while non-selected countries and legend items fade to low opacity. The visualization uses d3.geoNaturalEarth1 with d3.geoPath for projected SVG rendering, d3.scaleOrdinal with schemeSpectral for color mapping, and d3.zoom for panning. Data comes from the world-atlas TopoJSON and TSV files, processed through topojson.feature. Clicking a legend item toggles filtering on that value.

Choropleth Map with Interactive Filtering

This choropleth map displays world countries colored by economic classification, with an interactive color legend that filters which countries remain highlighted. Clicking a legend item dims all countries not in that category, while clicking the same item again clears the filter. The visualization uses d3.geoNaturalEarth1 for projection, d3.geoPath for rendering SVG paths, d3.scaleOrdinal with a spectral scheme for coloring, and d3.zoom for pan and zoom. Data comes from the world-atlas TopoJSON and TSV datasets, loaded via d3.json and d3.tsv.

Choropleth Map with Interactive Filtering

A world choropleth map colors countries by economic classification using a categorical ordinal scale. Clicking a legend item filters the map, dimming unselected countries and highlighting the chosen category while clicking again resets the view. The visualization is built with D3 v5, using `geoNaturalEarth1` and `geoPath` for map projection and rendering, with pan and zoom enabled via `d3.zoom`. Data comes from the World Atlas TopoJSON, and the legend uses SVG circles with click handlers.

Choropleth Map with Interactive Filtering

A choropleth map of world countries colored by economic group, with an interactive legend that filters the map to highlight countries matching a selected category. Users click legend items to toggle filtering, which dims all non-matching countries and slightly emphasizes the selected group. The visualization uses d3.geoNaturalEarth1 and d3.geoPath for map projection, d3.scaleOrdinal with d3.schemeSpectral for color encoding, and d3.zoom for pan/zoom. Data comes from the World Atlas TopoJSON and TSV files loaded via d3.tsv and d3.json.

Choropleth Map with Interactive Filtering

This choropleth map displays world countries colored by economic classification, with an interactive legend that filters the map to highlight selected categories while dimming others. Users can click legend items to toggle filtering, and the map supports zooming and panning via d3.zoom with geographic projection using d3.geoNaturalEarth1 and d3.geoPath. Data combines TopoJSON world geometry with TSV metadata, rendered as SVG paths with d3.v5.

Choropleth Map with Interactive Filtering

This choropleth map displays country-level economic classifications using a color scale based on world-atlas TopoJSON data. Users can click legend items to highlight countries matching that category while dimming others, and hover effects further emphasize individual countries. The visualization uses d3.geoPath with a geoNaturalEarth1 projection for map rendering, d3.zoom for panning and zooming, and d3.scaleOrdinal with schemeSpectral for color encoding. The legend and map are built as separate SVG components that re-render when the selection changes.

Choropleth Map with Interactive Filtering

This choropleth map displays countries colored by economic classification, with an interactive color legend allowing users to click a category and filter the map to highlight only matching countries while dimming others. Hovering reveals country names via tooltips, and the map supports zoom and pan. Built with D3 v5, it uses d3.geoPath and d3.geoNaturalEarth1 for projection, d3.scaleOrdinal with schemeSpectral for coloring, and d3.zoom for interaction. Data comes from TopoJSON world-atlas 50m, joined with TSV metadata storing economy type per country.
