Choropleth Map with Interactive Filtering

Choropleth Map with Interactive Filtering

A choropleth map of global economies uses color to encode each country's economic classification, with an interactive color legend that filters the map by category. Clicking a legend item dims non-matching countries, while a second click clears the filter; hovering over a country reveals its name and category via a title tooltip. The visualization combines d3.geoPath and geoNaturalEarth1 for map projection, d3.scaleOrdinal with schemeSpectral for colors, and d3.zoom for pan and zoom. Data comes from the World Atlas TopoJSON and TSV files.

Choropleth Map with Interactive Filtering

A choropleth map of global economies uses color to encode each country’s economic group, with an interactive color legend that filters the map by clicking a category. Pan and zoom via d3.zoom reveal spatial patterns, while hovering shows country names and values through SVG titles. The visualization is built with d3.geoNaturalEarth1 and d3.geoPath, using ordinal color scaling with d3.scaleOrdinal and d3.schemeSpectral. Data comes from the world-atlas TopoJSON and TSV files, rendered as SVG paths, with the legend updating opacity to dim unselected countries.

Choropleth Map with Interactive Filtering

A choropleth map of global economies uses color to encode income group for each country, with an interactive color legend that filters the map when clicked. Hovering over legend items dims countries not in the selected category, while clicking toggles filtering and zooms are supported. The visualization is built with d3.js v5, using d3.geoPath and d3.geoNaturalEarth1 for geographic projection, d3.scaleOrdinal with d3.schemeSpectral for coloring, and d3.zoom for pan/zoom. Data comes from the World Atlas TopoJSON and TSV files loaded via d3.json and d3.tsv.

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

This choropleth map colors countries by their economy category and includes an interactive color legend for filtering. Hovering a legend item highlights matching countries and dims all others, while clicking toggles the selection. The visualization uses d3.geoNaturalEarth1 and d3.geoPath for geographic projection, d3.scaleOrdinal with schemeSpectral for coloring, and d3.zoom for panning. Data comes from the world-atlas TopoJSON and TSV files, rendered as SVG paths with click-driven state updates.

Choropleth Map with Interactive Filtering

This choropleth map displays world economies by color, with an interactive legend that filters countries by economic category. Clicking a legend item dims non-matching countries while highlighting the selected group. The visualization uses d3.geoNaturalEarth1 projection with d3.geoPath to render TopoJSON data from the world-atlas package, while d3.scaleOrdinal with schemeSpectral assigns colors. Zoom and pan are enabled via d3.zoom, and clicking legend items toggles opacity and stroke styling through SVG attributes.

Choropleth Map with Interactive Filtering

This choropleth map visualizes world economies by color-coding countries according to their economic classification. Users can click legend categories to filter the map, highlighting matching countries while dimming others; clicking again resets the filter. The map uses d3.geoNaturalEarth1 projection and d3.geoPath for rendering, while d3.scaleOrdinal with d3.schemeSpectral supplies the color scale. Data comes from the world-atlas dataset, loaded via d3.tsv and topojson.feature.

Choropleth Map with Interactive Filtering

This interactive choropleth map visualizes global economic classifications using a color-coded world map, with a legend that filters countries by economy type. Users can click a legend category to highlight matching countries and dim others, and can click again to clear the filter. The visualization uses d3.geoPath with a geoNaturalEarth1 projection to render country boundaries from World Atlas TopoJSON and TSV data. Color assignments use d3.scaleOrdinal with the schemeSpectral palette, while d3.zoom enables panning and scaling. The SVG rendering includes hover effects that change country fill to white.
