A choropleth map colors countries by economic category using a spectral color scale, with an interactive legend that filters the map by clicking a category to highlight it. The map loads world geometry from TopoJSON and country metadata from TSV. Built with D3 v5, it uses `d3.geoPath` with a Natural Earth projection, `d3.zoom` for panning, and SVG for rendering. Clicking a legend item toggles selection, dimming non-matching countries and emphasizing the chosen group.

AI-generated description

Choropleth Map with Interactive Filtering

A choropleth map colors countries by economic classification using a spectral color scale, with an interactive legend that filters the map when clicked. Hovering over a legend item dims all countries except those matching the selected category, while clicking toggles the filter on and off. Built with D3 v5, the visualization uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering SVG paths, and `d3.zoom` for panning and zooming. Geographic data comes from the World Atlas TopoJSON dataset, with country names and economic groups loaded from a TSV file.

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 countries colored by economic grouping, with an interactive color legend that filters the map when clicked. Users can select a specific economic category to highlight those countries and dim all others, or click again to reset the view. Pan and zoom controls allow exploration of the global map. The visualization is built with D3 v5, using `d3.geoPath` and `d3.geoNaturalEarth1` for map projection, plus `d3.scaleOrdinal` and `d3.schemeSpectral` for color encoding. Country boundaries and metadata come from the world-atlas TopoJSON and TSV datasets.

Choropleth Map with Interactive Filtering

A choropleth map colors countries by economic category using an ordinal color scale derived from d3.scaleOrdinal and d3.schemeSpectral. Clicking a legend item filters the map, reducing the opacity of non-matching countries and highlighting the selected category. The map uses d3.geoNaturalEarth1 and d3.geoPath to render world features from TopoJSON data, while d3.zoom enables panning and zooming on the SVG. Hovering a country turns it red via CSS.

Choropleth Map with Interactive Filtering

A world choropleth map colors countries by their economy category, with an interactive color legend that filters which countries remain highlighted. Built with D3 v5, it uses `geoNaturalEarth1` projection with `geoPath` for geographic rendering, `zoom` for panning and scaling, and a `scaleOrdinal` with a spectral scheme for categorical colors. Data comes from TopoJSON world-atlas files merged with TSV metadata, and clicking a legend tick dims all non-matching countries.

Choropleth Map with Interactive Filtering

A choropleth map colors countries by economic classification using a D3 ordinal color scale, then allows interactive filtering through hover-adjacent clicks on the legend. The map renders with SVG and a natural Earth projection via `d3.geoPath`, while the legend items toggle opacity and highlight matching countries. Users can zoom and pan using `d3.zoom`, and the map loads world geometry from TopoJSON with economy data from a TSV file.

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.
