This interactive choropleth map visualizes global economic data, coloring each country on a natural Earth projection according to its economy category. Users can click a country to highlight it, dimming all others, or click a color legend to filter countries by economic classification, which also outlines matching countries in red. The example uses d3.geoPath for map rendering, d3.scaleOrdinal with a spectral color scheme, and d3.zoom for pan and zoom interactions. Country data is loaded from a TopoJSON file combined with a TSV file containing ISO country codes and economic classifications.

Choropleth map with interaction

This choropleth map displays global economic data, with each country colored according to its economy category. Clicking a color legend item filters the map, dimming non-matching countries and highlighting the selected category; clicking again clears the filter. The visualization uses d3.geoPath with a geoNaturalEarth1 projection to render country shapes from TopoJSON data, while d3.scaleOrdinal and schemeSpectral define the color encoding. d3.zoom enables panning and zooming, and the color legend uses d3 selections with click handlers for interaction.

Choropleth Map w Interactions

This choropleth map displays global economic groups using an ordinal color scale, where each country is colored by its economy category. Users can click legend items to highlight matching countries while dimming others, and hover over countries to see their name and economy value in a tooltip. The visualization uses d3.geoNaturalEarth1 projection with d3.geoPath to render country boundaries, and incorporates d3.scaleOrdinal with a spectral color scheme for categorical coloring. The map includes zoom functionality via d3.zoom, and data is loaded from the world-atlas package using d3.tsv and topojson.feature.

Choropleth Map with Interactive Filtering

This interactive choropleth map visualizes global economic classifications using a color-coded world map, with a legend that filters countries by economy type. Users can click a legend category to highlight matching countries and dim others, and can click again to clear the filter. The visualization uses d3.geoPath with a geoNaturalEarth1 projection to render country boundaries from World Atlas TopoJSON and TSV data. Color assignments use d3.scaleOrdinal with the schemeSpectral palette, while d3.zoom enables panning and scaling. The SVG rendering includes hover effects that change country fill to white.

Choropleth Map with Interactive Filtering

This choropleth map visualizes global economic classifications, with each country colored according to its economy category. Users can click items in the interactive color legend to filter the map, highlighting matching countries and dimming all others, while hovering over the legend reveals tooltips. The visualization uses d3.geoPath with a geoNaturalEarth1 projection to render the map from TopoJSON world data, and d3.scaleOrdinal with schemeSpectral to assign colors. Zoom and pan functionality are implemented via d3.zoom, and the legend filtering uses click handlers with opacity transitions.

Choropleth Map interactive

This interactive choropleth map colors countries by economic classification using a spectral color scale, with a legend showing the ordinal categories. Users can pan and zoom the map via d3.zoom, which applies a transform to the map group. The visualization loads world geometry from TopoJSON and joins it with tabular data from a TSV file, then renders the map with d3.geoPath and a Natural Earth projection. Hovering highlights a country in red, and tooltips display country names and their economy values.

Chloropleth Map Interactive

This interactive choropleth map displays world countries colored by their economic classification using an ordinal color scale. Users can click legend items to filter and highlight countries matching the selected economy type, with non-matching countries fading to low opacity. The map uses d3.geoNaturalEarth1 projection and d3.geoPath for rendering country boundaries as SVG paths, with d3.zoom enabling pan and zoom interactions. Data comes from TopoJSON world atlas files, while the interactive legend is built with custom d3 selections and click handlers.

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.
