This visualization presents a world choropleth map coloring countries by economic classification using a spectral color scale, with an interactive legend that filters highlighted countries on click. Built with D3 v5, it employs `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering, and `d3.zoom` for panning and zooming. Country data comes from the World Atlas TopoJSON and TSV files, while the legend uses `d3.scaleOrdinal` and `d3.schemeSpectral`. Hovering over a country turns it red, and the legend’s clickable ticks dim non-selected categories.

Choropleth Map with Interactive Filtering

A choropleth map colors countries by economic classification using a spectral color scale, with an interactive legend that filters the map when clicked. Hovering over a legend item dims all countries except those matching the selected category, while clicking toggles the filter on and off. Built with D3 v5, the visualization uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering SVG paths, and `d3.zoom` for panning and zooming. Geographic data comes from the World Atlas TopoJSON dataset, with country names and economic groups loaded from a TSV file.

Choropleth Map with Interactive Filtering

This choropleth map colors countries by economic classification using a spectral color scale, with an interactive legend that filters map regions by clicking legend items. The visualization combines a world map rendered with d3.geoPath and d3.geoNaturalEarth1, a colorLegend with clickable circles, and d3.zoom for panning and zooming. Country data comes from the world-atlas TopoJSON and TSV datasets, with hover highlighting and tooltips showing country names and values.

Choropleth Map with Interactive Filtering

This choropleth map colors countries by economic classification using a spectral color scale, with a clickable legend that filters the map to highlight selected categories and dim non-matching countries. Built with D3 v5, the visualization renders GeoJSON features via `d3.geoPath` with a Natural Earth projection, uses `d3.scaleOrdinal` and `d3.schemeSpectral` for color mapping, and supports zooming through `d3.zoom`. Data is loaded from the world-atlas TopoJSON and TSV files.

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

This choropleth map colors countries by economic classification using a spectral color scale, with a natural Earth projection rendered as SVG paths. An interactive legend allows users to click individual color categories, though the selection only logs to the console rather than filtering the map. The visualization loads world topology from the world-atlas TopoJSON dataset and joins country names from TSV data. The choropleth uses d3.geoPath, d3.scaleOrdinal with schemeSpectral, and d3.zoom for panning and zooming, while the custom colorLegend module handles the clickable legend UI.

Choropleth Map with Interactive Filtering

A world choropleth map colors countries by economic classification using a categorical ordinal scale. Clicking a legend item filters the map, dimming unselected countries and highlighting the chosen category while clicking again resets the view. The visualization is built with D3 v5, using `geoNaturalEarth1` and `geoPath` for map projection and rendering, with pan and zoom enabled via `d3.zoom`. Data comes from the World Atlas TopoJSON, and the legend uses SVG circles with click handlers.

Choropleth Map Interactive

This interactive choropleth map displays countries colored by their economy category, using a spectral color scale and a natural Earth projection. Users can click legend swatches to highlight matching regions while dimming others. The visualization is built with D3 v5 modules including `geoNaturalEarth1`, `geoPath`, and `zoom`, rendering vector shapes as SVG. It loads geographic data from the World Atlas TopoJSON and TSV files, processing them via `topojson.feature`. A dedicated color legend component supports selection filtering, while CSS hover effects emphasize individual countries.
