A choropleth map colors countries by economic classification using an ordinal color scale and the D3 geoNaturalEarth1 projection. Users click legend items to filter the map’s displayed categories, with non-selected legend entries and map countries dimmed to 20% opacity. The visualization relies on d3.geoPath, d3.zoom for panning, and topojson to convert world-atlas TopoJSON data into GeoJSON features.

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 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.

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

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

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

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.

Chloropleth Map with Interactive Filtering

A choropleth map colors countries by economic classification using an ordinal color scale, with a linked legend for interactive filtering. Clicking a legend category dims non-matching countries and highlights selected ones, while clicking again clears the filter. The visualization uses d3.geoPath and d3.geoNaturalEarth1 for map projection, and d3.zoom for pan and zoom. Data comes from world-atlas TopoJSON and TSV files; colors are applied via d3.scaleOrdinal with the GnBu scheme.

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.
