Choropleth Map with Interactive Filtering

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 with Interactive Filtering

A choropleth map displays global economic classifications by country, with a color legend encoding each category. Clicking a legend item filters the map, dimming non-matching countries while highlighting the selected group. Hovering reveals country names and values via tooltips. Built with D3 v5, it uses `geoNaturalEarth1` and `geoPath` for SVG map rendering, `scaleOrdinal` with `schemeSpectral` for colors, and `zoom` for panning. Data comes from TopoJSON world-atlas merged with TSV metadata.

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

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 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

A choropleth map displays countries colored by economic classification, with a legend of color swatches. Clicking a legend item filters the map to highlight only countries in that category, dimming all others, while hovering over a legend item reveals its effect. Built with D3 v5, the visualization uses `geoNaturalEarth1` and `geoPath` for the map projection and rendering, plus `scaleOrdinal` with `schemeSpectral` for colors. Geographic data comes from the World Atlas TopoJSON and TSV files.

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

A choropleth map colors countries by economic classification using an ordinal color scale. Clicking a legend entry filters the map, dimming non-matching countries while highlighting the selected category. The visualization uses d3.geoNaturalEarth1, d3.geoPath, and d3.zoom for pan and zoom, with d3.scaleOrdinal and schemeSpectral for coloring. Data comes from the World Atlas TopoJSON and TSV files loaded via d3.json and d3.tsv, rendered as SVG with clickable legend ticks.
