A choropleth map of world economies displays countries colored with an ordinal spectral scale. Users click a legend to filter the map, highlighting matching countries and dimming all others. Built with D3 v5, the map uses a natural Earth projection with `d3.geoPath` and `d3.geoNaturalEarth1`. Economic data comes from a TSV file loaded via `d3.tsv`, while country boundaries are processed from TopoJSON using the `topojson` library. The visualization supports zooming and panning via the `d3.zoom` API.

Choropleth Map with Interactive Filtering

This choropleth map displays world economies using a spectral color scale, with each country colored according to its economic classification. Users can click legend items to filter the map, highlighting countries matching the selected economy while dimming others. The visualization uses D3 v5 APIs including `d3.geoPath`, `d3.geoNaturalEarth1`, `d3.scaleOrdinal`, and `d3.schemeSpectral` to render SVG paths. Data comes from a World Atlas TopoJSON file joined with TSV metadata, and interactive zooming is enabled through D3's `zoom` event system.

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

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 displays world economies using a color gradient, with an interactive legend that filters countries by economic category. Users can zoom and pan the map, and clicking a legend entry dims non-matching countries while highlighting the selected group. The visualization uses d3.geoNaturalEarth1 projection, d3.geoPath for rendering SVG paths, and d3.zoom for navigation. Data comes from the world-atlas TopoJSON and TSV datasets, with unemployment type and population shown in tooltips. The color scale uses d3.schemeSpectral, and legend interactions are handled through d3 event listeners.

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!

This choropleth map visualizes world economies using a natural Earth projection, with each country colored by economic category through d3.scaleOrdinal and d3.schemeSpectral. Hovering highlights countries, while clicking a legend item filters the map to show only matching categories, dimming others via opacity adjustments. Built with d3.geoPath, d3.geoNaturalEarth1, and d3.zoom for panning, the data comes from TopoJSON and TSV files. The color legend uses d3 event handlers for interactive filtering.

Choropleth Map with interactive filtering

This choropleth map visualizes the world’s economies using color-coded countries, with interactive filtering by clicking legend items to highlight specific economic categories. The map uses an Equirectangular projection and supports zooming and panning. Built with D3 v5, it employs `geoPath` and `geoNaturalEarth1` for geographic rendering, while a clickable `colorLegend` toggles opacity and highlights selected regions. Data originates from the World Atlas TopoJSON and TSV files, rendered as SVG elements.
