This choropleth map shows global economic data by country, with an interactive color legend that filters countries by economy category. Users click legend items to highlight matching countries and fade others, and they can hover over countries to see their name and value in a tooltip. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, with a spectral ordinal color scale, while the legend and map both respond to clicks through D3's event handling. World country boundaries and metadata come from the world-atlas package, loaded via `d3.tsv` and `d3.json`.

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 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.

Choropleth Map With Interactive Filtering

A choropleth map of world countries colored by economy, with an interactive color legend that filters the map to highlight countries in a selected category. Clicking a legend entry dims non-matching countries and increases their stroke width; clicking again clears the filter. Built with D3 v5, the visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to render topojson country features from the world-atlas dataset, with `d3.scaleOrdinal` and `schemeSpectral` for colors.

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 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 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.
