This choropleth map visualizes countries colored by economic classification, with interactive filtering through a clickable legend that dims unselected regions. The map uses an equal-Earth projection via d3.geoPath and supports zooming through d3.zoom. World country boundaries come from TopoJSON, enriched with ISO codes from a TSV lookup. Selection updates path opacity and stroke-width, while the legend animates circle radii using transition().duration().

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 visualizes global economic classifications by country, with interactive filtering through a clickable color legend that updates the displayed data. The map uses a dark-blue sphere background with semi-transparent colored regions, rendered via SVG paths generated by `d3.geoPath` with an Equal Earth projection. Users can zoom and pan using `d3.zoom`, while the legend employs `d3.scaleOrdinal` with a spectral color scheme and animated transitions. Data combines TopoJSON country boundaries from world-atlas with TSV metadata, processed through `Promise.all` and the `feature` API.

Choropleth Map with Interactive Filtering

A choropleth map displays world countries colored by economic classification, with an interactive legend that filters which countries remain highlighted. Users click legend categories to isolate specific economic groups, dimming non-matching countries to 10% opacity. The visualization uses d3.geoNaturalEarth1 and d3.geoPath for map projection, d3.zoom for panning, and a d3.scaleOrdinal with schemeSpectral for coloring. Data combines TopoJSON world geometry with TSV metadata from the world-atlas package. The SVG rendering supports hover effects and a legend built with custom SVG groups and circles.

Choropleth Map with Interactive Filtering

This choropleth map displays global economic classifications using color-coded countries on a natural Earth projection. Users can click legend items to filter and highlight specific categories while dimming others. The visualization uses d3.geoPath to render country shapes from TopoJSON data and d3.scaleOrdinal with a spectral color scheme. Interactive zooming is implemented with d3.zoom, while legend clicks trigger re-rendering with adjusted opacity values.

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

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.
