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 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

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

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.

Choropleth Map with Interactive Filtering

A choropleth map displays global economic classifications by country, with a color legend encoding each category. Clicking a legend item filters the map, dimming non-matching countries while highlighting the selected group. Hovering reveals country names and values via tooltips. Built with D3 v5, it uses `geoNaturalEarth1` and `geoPath` for SVG map rendering, `scaleOrdinal` with `schemeSpectral` for colors, and `zoom` for panning. Data comes from TopoJSON world-atlas merged with TSV metadata.

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 global economies by country, colored with a spectral ordinal scale. Users click legend items to filter the map, which highlights matching countries and dims others. The visualization uses D3 v5 with `geoPath`, `geoNaturalEarth1`, and a `zoom` interaction, alongside a custom color legend built with `scaleOrdinal` and `schemeSpectral`. Data merges TopoJSON country boundaries with TSV attributes loaded from the `world-atlas` package.

Choropleth Map with Interactive Filtering

A choropleth map colors countries by economic classification using D3's `geoNaturalEarth1` projection and `geoPath`, with an ordinal color scale from `schemeSpectral`. Clicking a legend item filters the map by highlighting matching countries and dimming others, while the sphere fades to emphasize the selection. The visualization loads country boundaries from TopoJSON world-atlas data and supports pan and zoom via `d3.zoom`, with tooltips showing country names and values.

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.
