A choropleth map of global economies uses ordinal color encoding, with a legend that lets users click color swatches to filter countries by economic group. Non-matching countries dim to low opacity, and the selected legend item highlights its corresponding category on the map. The visualization is built with D3 v5, using `d3.geoPath` and `geoNaturalEarth1` for map projection, `scaleOrdinal` with `schemeSpectral` for colors, and `zoom` for panning. Data comes from TopoJSON world-atlas files, with SVG rendering for all 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 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

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 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 world economies by color, showing how countries group by income category. Users hover over color legend items to filter the map, which dims non-matching countries and highlights selected ones. The visualization uses D3 v5 APIs including `geoNaturalEarth1` and `geoPath` for map projection, `zoom` for panning, and `scaleOrdinal` with `schemeSpectral`. It loads geographic boundaries from TopoJSON and economic data from TSV in `loadAndProcessData`. Interactive legend clicks trigger opacity changes through `colorLegend`, with SVG rendering throughout.

Choropleth Map with Interactive Filtering

A choropleth map displays global economic classifications by country, with an interactive color legend that filters the map by hovering or clicking on a category. The d3-scaleOrdinal and schemeSpectral color scale map each economy type to a distinct color, while d3-geoPath and geoNaturalEarth1 render the world geometry from TopoJSON data. Clicking a legend item dims non-matching countries and highlights the selected group, with zoom support via d3.zoom. The map uses SVG and d3.v5 for all rendering and interaction.

Choropleth Map with Interactive filtering

This choropleth map of world economies uses color to encode categorical economic data, with an interactive legend that filters which countries are highlighted. Clicking a legend value dims all countries not in that category while emphasizing those that match. The visualization is built with d3.geoPath and d3.geoNaturalEarth1 for map projections, d3.scaleOrdinal with schemeSpectral for coloring, and a custom colorLegend component with click handlers. Country data comes from World Atlas TopoJSON and TSV files, rendered as SVG paths.
