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.

AI-generated description

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

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

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 global economic classifications by country, with an interactive color legend that enables filtering by category. Selecting a legend item highlights matching countries while dimming others, and clicking again clears the filter. The visualization uses d3.geoPath with a geoNaturalEarth1 projection to render world boundaries from TopoJSON data (World Atlas 50m), styled as SVG paths. The d3.scaleOrdinal with schemeSpectral drives the color encoding, while d3.zoom provides pan and zoom transformation on the map group.

Choropleth Map with Interactive Filtering

This choropleth map colors countries by their economic classification using a spectral color scale, with an interactive legend that filters the map by clicking a category value. The visualization uses d3.geoNaturalEarth1 and d3.geoPath to project and draw the geographic features, while d3.zoom enables panning and zooming on the SVG canvas. The legend, built with custom D3 selections, dims unselected categories and allows toggling filters. Country data comes from the world-atlas TopoJSON dataset, enriched with economic metadata from a TSV file.

Choropleth Map with Interactive Filtering

This choropleth map displays global economic classifications by country, with a color-coded legend that doubles as an interactive filter. Clicking a legend item highlights matching countries and dims all others on the map. The visualization uses d3.geoPath and d3.geoNaturalEarth1 for the map projection, while d3.scaleOrdinal with schemeSpectral drives the color encoding. Hovering over legend items updates their opacity, and d3.zoom enables pan and zoom interactions. Country data comes from the World Atlas TopoJSON and TSV datasets loaded via d3.json and d3.tsv.
