This choropleth map colors world countries by economic classification using an ordinal color scale and a natural Earth projection. Users click legend entries to filter the map, dimming non-selected countries and highlighting the chosen category. The visualization uses d3.geoPath for geographic rendering, d3.zoom for panning, and a d3.scaleOrdinal with a spectral scheme. Country boundaries and metadata come from the World Atlas TopoJSON and TSV datasets, with interactive legend filters implemented in SVG.

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 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

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

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 country-level economic classifications using a color scale based on world-atlas TopoJSON data. Users can click legend items to highlight countries matching that category while dimming others, and hover effects further emphasize individual countries. The visualization uses d3.geoPath with a geoNaturalEarth1 projection for map rendering, d3.zoom for panning and zooming, and d3.scaleOrdinal with schemeSpectral for color encoding. The legend and map are built as separate SVG components that re-render when the selection changes.

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.
