Forked from Choropleth Map with Interactive Filtering

This choropleth map displays world countries colored by economic classification, with an interactive color legend that filters the map when clicked. Hovering reveals country names and values via tooltips, while non-selected countries and legend items fade to low opacity. The visualization uses d3.geoNaturalEarth1 with d3.geoPath for projected SVG rendering, d3.scaleOrdinal with schemeSpectral for color mapping, and d3.zoom for panning. Data comes from the world-atlas TopoJSON and TSV files, processed through topojson.feature. Clicking a legend item toggles filtering on that value.

Choropleth Map with Interactive Filtering

This choropleth map displays world countries colored by economic classification, with an interactive color legend that filters which countries remain highlighted. Clicking a legend item dims all countries not in that category, while clicking the same item again clears the filter. The visualization uses d3.geoNaturalEarth1 for projection, d3.geoPath for rendering SVG paths, d3.scaleOrdinal with a spectral scheme for coloring, and d3.zoom for pan and zoom. Data comes from the world-atlas TopoJSON and TSV datasets, loaded via d3.json and d3.tsv.

Choropleth Map with Interactive Filtering

A choropleth map displays world countries colored by economic classification, with an interactive legend that filters which countries remain highlighted. Users click legend categories to isolate specific economic groups, dimming non-matching countries to 10% opacity. The visualization uses d3.geoNaturalEarth1 and d3.geoPath for map projection, d3.zoom for panning, and a d3.scaleOrdinal with schemeSpectral for coloring. Data combines TopoJSON world geometry with TSV metadata from the world-atlas package. The SVG rendering supports hover effects and a legend built with custom SVG groups and circles.

Choropleth Map with Interactive Filtering

A choropleth map of world countries colored by economic group, with an interactive legend that filters the map to highlight countries matching a selected category. Users click legend items to toggle filtering, which dims all non-matching countries and slightly emphasizes the selected group. The visualization uses d3.geoNaturalEarth1 and d3.geoPath for map projection, d3.scaleOrdinal with d3.schemeSpectral for color encoding, and d3.zoom for pan/zoom. Data comes from the World Atlas TopoJSON and TSV files loaded via d3.tsv and d3.json.

Choropleth Map with Interactive Filtering

This choropleth map shows countries colored by economic grouping, with a color legend that filters the map when clicked. Clicking a legend item dims unselected countries and highlights those matching the chosen category. The visualization uses d3.geoPath with d3.geoNaturalEarth1 for projection, d3.zoom for panning, and d3.scaleOrdinal with schemeSpectral for colors. Country boundaries come from the world-atlas TopoJSON dataset, with hover effects and tooltips showing country names and values.

Choropleth Map with Interactive Filtering

This choropleth map displays country-level economic classifications using a color scale based on world-atlas TopoJSON data. Users can click legend items to highlight countries matching that category while dimming others, and hover effects further emphasize individual countries. The visualization uses d3.geoPath with a geoNaturalEarth1 projection for map rendering, d3.zoom for panning and zooming, and d3.scaleOrdinal with schemeSpectral for color encoding. The legend and map are built as separate SVG components that re-render when the selection changes.

Choropleth Map with Interactive Filtering

A choropleth map visualizes countries by economic classification, with a color legend that filters the map when clicked. Hovering over legend items highlights matching countries, while clicking isolates one category and dims others. The map uses d3.geoNaturalEarth1, d3.geoPath, and d3.zoom for panning and zooming, while d3.scaleOrdinal with schemeSpectral assigns colors. Data comes from TopoJSON world-atlas and TSV metadata, rendered as SVG paths. Interactive filtering is implemented via click handlers on legend groups, adjusting opacity and stroke width of country paths.
