A world choropleth map colors countries by economic classification using a categorical ordinal scale. Clicking a legend item filters the map, dimming unselected countries and highlighting the chosen category while clicking again resets the view. The visualization is built with D3 v5, using `geoNaturalEarth1` and `geoPath` for map projection and rendering, with pan and zoom enabled via `d3.zoom`. Data comes from the World Atlas TopoJSON, and the legend uses SVG circles with click handlers.

Choropleth Map with Interactive Filtering

A world choropleth map colors countries by economic classification, with a linked legend that filters the map when a category is clicked. Hovering over the legend dims non-matching countries to 10% opacity, while the selected category is highlighted. The visualization uses D3 v5’s `geoNaturalEarth1` projection, `geoPath`, and `zoom` for panning, alongside a custom ordinal `scaleOrdinal` with the `schemeSpectral` range. Map data comes from the World Atlas TopoJSON and TSV files.

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 an ordinal color scale. Clicking a legend entry filters the map, dimming non-matching countries while highlighting the selected category. The visualization uses d3.geoNaturalEarth1, d3.geoPath, and d3.zoom for pan and zoom, with d3.scaleOrdinal and schemeSpectral for coloring. Data comes from the World Atlas TopoJSON and TSV files loaded via d3.json and d3.tsv, rendered as SVG with clickable legend ticks.

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 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 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

A choropleth map colors countries by economic classification, with a categorical color legend that doubles as a filter. Clicking a legend category dims non-matching countries and highlights the selected class, while zoom and pan are enabled via d3.zoom. The map uses d3.geoPath with a Natural Earth projection, rendering TopoJSON data from the World Atlas, and d3.scaleOrdinal with schemeSpectral assigns colors. Hover styling also highlights individual countries.

Choropleth Map with Interactive Filtering

A choropleth map displays countries colored by economic classification, with a legend of color swatches. Clicking a legend item filters the map to highlight only countries in that category, dimming all others, while hovering over a legend item reveals its effect. Built with D3 v5, the visualization uses `geoNaturalEarth1` and `geoPath` for the map projection and rendering, plus `scaleOrdinal` with `schemeSpectral` for colors. Geographic data comes from the World Atlas TopoJSON and TSV files.
