A choropleth map of global economies color-coded by development category, with an interactive legend that filters highlighted countries by clicking category swatches. Built with D3 v5, it combines `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.zoom` for panning and zooming the SVG-rendered map, while `d3.scaleOrdinal` and `schemeSpectral` assign colors from world-atlas TopoJSON data. Clicking a legend item dims non-matching countries and toggles the selection; tooltips show country names and values via SVG `<title>` elements.

Choropleth Map with Interactive Filtering

A choropleth map of global economies uses color to distinguish categories, with an interactive legend enabling users to click a category and highlight matching countries while dimming the rest. Built with D3 v5, the visualization uses `geoNaturalEarth1` and `geoPath` for map projection, `scaleOrdinal` and `schemeSpectral` for coloring, and `zoom` for panning. Data comes from the World Atlas TopoJSON and TSV files. Hovering reveals country names and values via SVG `title` elements.

Choropleth Map with Interactive Filtering

A choropleth map of global economies uses color to encode each country’s economic group, with an interactive color legend that filters the map by clicking a category. Pan and zoom via d3.zoom reveal spatial patterns, while hovering shows country names and values through SVG titles. The visualization is built with d3.geoNaturalEarth1 and d3.geoPath, using ordinal color scaling with d3.scaleOrdinal and d3.schemeSpectral. Data comes from the world-atlas TopoJSON and TSV files, rendered as SVG paths, with the legend updating opacity to dim unselected countries.

Choropleth Map With Interactive Filtering

A choropleth map of world countries colored by economy, with an interactive color legend that filters the map to highlight countries in a selected category. Clicking a legend entry dims non-matching countries and increases their stroke width; clicking again clears the filter. Built with D3 v5, the visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to render topojson country features from the world-atlas dataset, with `d3.scaleOrdinal` and `schemeSpectral` for colors.

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 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

A choropleth map of global economies uses color to encode income group for each country, with an interactive color legend that filters the map when clicked. Hovering over legend items dims countries not in the selected category, while clicking toggles filtering and zooms are supported. The visualization is built with d3.js v5, using d3.geoPath and d3.geoNaturalEarth1 for geographic projection, d3.scaleOrdinal with d3.schemeSpectral for coloring, and d3.zoom for pan/zoom. Data comes from the World Atlas TopoJSON and TSV files 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.
