This choropleth map displays country-level economic data using a color scale, with a legend allowing viewers to filter the map by clicking a specific economic category. The map uses a natural Earth projection through `d3.geoNaturalEarth1` and `d3.geoPath`, rendering country boundaries as SVG paths. Filtering dims non-selected countries and highlights the chosen one, while the legend’s interactive ticks use `d3.scaleOrdinal` and `schemeSpectral` for colors. Data is loaded from the world-atlas TSV and TopoJSON files, with interactive zoom via `d3.zoom`.

Choropleth Map with Interactive Filtering

This choropleth map displays global economic data using a color scale, where users can click on color legend items to interactively filter the map. The map renders countries as SVG paths using `d3.geoPath` with a Natural Earth projection, while the legend employs `d3.scaleOrdinal` with a spectral color scheme. Hovering reveals country names and values via `<title>` elements. Clicking a legend category dims non-matching countries, and zooming is enabled through the `d3.zoom` module. Data originates from the world-atlas TopoJSON and TSV files.

Choropleth Map with Interactive Filtering

A choropleth map of global economic data, colored by country using a spectral ordinal scale, lets viewers filter countries by clicking a color legend. The map renders with an SVG projection via `d3.geoNaturalEarth1` and `d3.geoPath`, supporting pan and zoom through `d3.zoom`. Legend clicks toggle highlighting of matching countries, dimming others. Country data merges TopoJSON geometries with TSV attributes from the world-atlas dataset, and legend interactions redraw both map and legend.

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

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

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

This choropleth map shows global economic data by country, with an interactive color legend that filters countries by economy category. Users click legend items to highlight matching countries and fade others, and they can hover over countries to see their name and value in a tooltip. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, with a spectral ordinal color scale, while the legend and map both respond to clicks through D3's event handling. World country boundaries and metadata come from the world-atlas package, loaded via `d3.tsv` and `d3.json`.

Choropleth Map with Interactive Filtering

A choropleth map displays countries colored by economic grouping, with a legend of color categories that users can click to highlight matching regions and fade all others. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, while the legend employs scale-ordinal colors from `schemeSpectral` and interactive click handlers. Panning and zooming are enabled through `d3.zoom`. The geographic data comes from the World Atlas TopoJSON, with ISO country mappings joined from TSV metadata.
