This choropleth map displays global economic classifications by country using color-coded regions. Users can filter the map by clicking legend categories, which dims non-matching countries and highlights those with the selected value. The visualization uses d3.geoPath with a geoNaturalEarth1 projection to render SVG map paths, while d3.scaleOrdinal and schemeSpectral assign colors. Data is loaded from world-atlas TopoJSON and TSV files, and interactions rely on the d3.event zoom and legend click handlers.

d3 Choropleth Map with Interactive Filtering

This choropleth map displays global economic data, coloring each country according to its economy category. Users can click a color in the legend to filter the map, highlighting matching countries and dimming others, with the sphere and non-matching countries reduced in opacity. The visualization uses the d3.geoPath and d3.geoNaturalEarth1 projections to render geographic shapes, while d3.scaleOrdinal and d3.schemeSpectral drive the color assignments. Geographic and tabular data are loaded from the World Atlas TopoJSON and TSV files via d3.json and d3.tsv.

Choropleth Map with Interactive filtering

This choropleth map displays global economic classifications by country, with an interactive color legend that enables filtering by category. Selecting a legend item highlights matching countries while dimming others, and clicking again clears the filter. The visualization uses d3.geoPath with a geoNaturalEarth1 projection to render world boundaries from TopoJSON data (World Atlas 50m), styled as SVG paths. The d3.scaleOrdinal with schemeSpectral drives the color encoding, while d3.zoom provides pan and zoom transformation on the map group.

Choropleth Map with Interactive Filtering

This choropleth map displays global economic classifications using color-coded countries on a natural Earth projection. Users can click legend items to filter and highlight specific categories while dimming others. The visualization uses d3.geoPath to render country shapes from TopoJSON data and d3.scaleOrdinal with a spectral color scheme. Interactive zooming is implemented with d3.zoom, while legend clicks trigger re-rendering with adjusted opacity values.

Choropleth Map with interactive filtering

This choropleth map shows global economic classifications, with countries colored by category. Clicking a legend entry filters the map, dimming non-matching countries and highlighting the selected one while zooming and panning remain available. The visualization uses d3.geoNaturalEarth1 projection, d3.geoPath for rendering, and d3.zoom for interaction. Data comes from the World Atlas TopoJSON and TSV files, with a d3.scaleOrdinal and schemeSpectral colormap driving the legend and fills.

Choropleth Map with Interactive Filtering

This choropleth map displays global economic classifications by country, with a color-coded legend that doubles as an interactive filter. Clicking a legend item highlights matching countries and dims all others on the map. The visualization uses d3.geoPath and d3.geoNaturalEarth1 for the map projection, while d3.scaleOrdinal with schemeSpectral drives the color encoding. Hovering over legend items updates their opacity, and d3.zoom enables pan and zoom interactions. Country data comes from the World Atlas TopoJSON and TSV datasets loaded via d3.json and d3.tsv.

Choropleth Map with Interactive Filtering

This choropleth map visualizes global economic classifications, with each country colored according to its economy category. Users can click items in the interactive color legend to filter the map, highlighting matching countries and dimming all others, while hovering over the legend reveals tooltips. The visualization uses d3.geoPath with a geoNaturalEarth1 projection to render the map from TopoJSON world data, and d3.scaleOrdinal with schemeSpectral to assign colors. Zoom and pan functionality are implemented via d3.zoom, and the legend filtering uses click handlers with opacity transitions.
