This interactive choropleth map visualizes country-level economic data from the World Atlas, rendered as SVG projections using D3’s `geoNaturalEarth1` and `geoPath` APIs. Users click countries to highlight them, which dims all others, and adjust the categorical color legend to filter which economies appear vivid. A color scale from `scaleOrdinal` with `schemeSpectral` maps economy types, while pan and zoom controls rely on D3’s `zoom` event. Country data combines TSV attributes with TopoJSON geometry via `topojson.feature`.

Choropleth Map with Interactive Filtering

This choropleth map displays country-level economic data using a color scale, with a legend allowing viewers to filter the map by clicking a specific economic category. The map uses a natural Earth projection through `d3.geoNaturalEarth1` and `d3.geoPath`, rendering country boundaries as SVG paths. Filtering dims non-selected countries and highlights the chosen one, while the legend’s interactive ticks use `d3.scaleOrdinal` and `schemeSpectral` for colors. Data is loaded from the world-atlas TSV and TopoJSON files, with interactive zoom via `d3.zoom`.

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 visualizes the world's economies, coloring each country according to its economic classification. Users can zoom and pan the map via `d3.zoom`, while the color legend offers an interactive click handler, though its filtering effect is not implemented. The visualization loads geographic data from the world-atlas TopoJSON and TSV files, using `d3.geoPath` with a `geoNaturalEarth1` projection to render countries as SVG paths. A spectral color scale maps economy categories to hues, and hovering highlights a country in coral.

Choropleth Map with Interactive Filtering

This choropleth map colors world countries by economy category using a sequential color scale, with an interactive legend that filters the map by clicking a category. The map renders geographic features with `d3.geoPath` and `d3.geoNaturalEarth1`, while the legend circles respond to clicks to toggle the selected category, dimming non-matching countries. Pan and zoom are enabled via `d3.zoom`. Data comes from the World Atlas TopoJSON and TSV files, processed with TopoJSON’s `feature` method.

Interactive Filtering

A choropleth map of global economies uses color to encode categorical income groups, with a linked legend enabling interactive filtering. Clicking a legend category dims unmatched countries and the map sphere, while highlighting the selected group on both map and legend. The visualization employs d3.geoPath and d3.geoNaturalEarth1 for map projection, d3.zoom for pan and zoom, and d3.scaleOrdinal with schemeSpectral for color encoding. Data comes from the World Atlas TopoJSON and TSV files, rendered as SVG.

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.

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

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.
