This choropleth map visualizes global economies by country using an ordinal color scale based on the world-atlas TopoJSON dataset. Users can click legend entries to filter the map, highlighting matching countries while dimming others, and zoom and pan through d3.zoom. The d3.geoNaturalEarth1 projection and d3.geoPath render the SVG paths, with interactivity built via d3.scaleOrdinal, d3.schemeSpectral, and event-driven re-rendering.

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

This choropleth map displays global economies using color-coded countries, with interactive filtering through a clickable color legend. Hovering over legend items dims non-matching countries, while clicking toggles filtering and highlights selected categories. The visualization uses d3.geoPath with a geoNaturalEarth1 projection for map rendering, d3.scaleOrdinal with schemeSpectral for coloring, and d3.zoom for panning. Data comes from TopoJSON world-atlas files, with country names and economy classifications merged from TSV metadata.

Choropleth Map with Interactive Filtering

A choropleth map displays global economies using color coding derived from world-atlas TopoJSON data, with countries shaded by income group. Users can filter the map by clicking color legend items, which highlights matching countries and dims others. The visualization uses d3.geoNaturalEarth1 projections, d3.geoPath for country outlines, d3.zoom for panning, and d3.scaleOrdinal with schemeSpectral colors. Hovering changes country fill to red, and tooltips reveal country names and values.

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 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 visualizes world economies by color-coding countries according to their economic classification. Users can click legend categories to filter the map, highlighting matching countries while dimming others; clicking again resets the filter. The map uses d3.geoNaturalEarth1 projection and d3.geoPath for rendering, while d3.scaleOrdinal with d3.schemeSpectral supplies the color scale. Data comes from the world-atlas dataset, loaded via d3.tsv and topojson.feature.

Choropleth Map with Interactive Filtering

A choropleth map of global economies uses color to encode each country's economic classification, with an interactive color legend that filters the map by category. Clicking a legend item dims non-matching countries, while a second click clears the filter; hovering over a country reveals its name and category via a title tooltip. The visualization combines d3.geoPath and geoNaturalEarth1 for map projection, d3.scaleOrdinal with schemeSpectral for colors, and d3.zoom for pan and zoom. Data comes from the World Atlas TopoJSON and TSV files.

Choropleth Map with Interactive Filtering

This choropleth map displays global economic data using a color scale, where users can click on color legend items to interactively filter the map. The map renders countries as SVG paths using `d3.geoPath` with a Natural Earth projection, while the legend employs `d3.scaleOrdinal` with a spectral color scheme. Hovering reveals country names and values via `<title>` elements. Clicking a legend category dims non-matching countries, and zooming is enabled through the `d3.zoom` module. Data originates from the world-atlas TopoJSON and TSV files.
