This choropleth map displays countries colored by economic classification, with an interactive color legend allowing users to click a category and filter the map to highlight only matching countries while dimming others. Hovering reveals country names via tooltips, and the map supports zoom and pan. Built with D3 v5, it uses d3.geoPath and d3.geoNaturalEarth1 for projection, d3.scaleOrdinal with schemeSpectral for coloring, and d3.zoom for interaction. Data comes from TopoJSON world-atlas 50m, joined with TSV metadata storing economy type per country.

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 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 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

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

A choropleth map colors countries by economic classification using a spectral color scale, with an interactive legend that filters the map when clicked. Hovering over a legend item dims all countries except those matching the selected category, while clicking toggles the filter on and off. Built with D3 v5, the visualization uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering SVG paths, and `d3.zoom` for panning and zooming. Geographic data comes from the World Atlas TopoJSON dataset, with country names and economic groups loaded from a TSV file.

Choropleth Map with Interactive Filtering

This choropleth map colors countries by their economy category and includes an interactive color legend for filtering. Hovering a legend item highlights matching countries and dims all others, while clicking toggles the selection. The visualization uses d3.geoNaturalEarth1 and d3.geoPath for geographic projection, d3.scaleOrdinal with schemeSpectral for coloring, and d3.zoom for panning. Data comes from the world-atlas TopoJSON and TSV files, rendered as SVG paths with click-driven state updates.

Choropleth Map with Interactive Filtering

This choropleth map displays countries colored by economic classification, with an interactive legend that filters map features by clicking on a category. The visualization uses d3.geoNaturalEarth1 projection with d3.geoPath to render country boundaries, while the color legend applies d3.scaleOrdinal with schemeSpectral. Pan and zoom are handled through d3.zoom. Data comes from the world-atlas TopoJSON dataset paired with TSV metadata, and filtering dims non-selected countries while highlighting the chosen economic group.

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.
