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 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 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.

Choropleth Map with Interactive Filtering

This choropleth map displays global economic classifications with an interactive legend that filters countries by color value. Clicking a legend item isolates the corresponding economy type, dimming non-matching countries to 10% opacity, while hovering over legend entries updates their clarity. The visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` for map projection, `d3.zoom` for panning and zooming, and `d3.scaleOrdinal` with `d3.schemeSpectral` for color encoding. World geometry comes from TopoJSON data loaded via `d3.json`, with country names and economy attributes merged from TSV data.

Choropleth Map with Interactive filtering

This choropleth map displays global economic classifications by country, with an interactive color legend that filters the map to a selected category. Users click legend items to dim non-matching countries and highlight the chosen group, while zooming is supported via d3.zoom. The visualization uses d3.geoNaturalEarth1 projection and d3.geoPath to render world features from TopoJSON data, with d3.scaleOrdinal and d3.schemeSpectral mapping economies to colors. Hover states change country fills to red, and tooltips show country names and values.

Choropleth Map with Interactive Filtering

This choropleth map displays global economic classifications by country, with an interactive legend that filters highlighted regions. Hovering over a color legend item dims all non-matching countries to 10% opacity, while the selected category remains fully visible and gains a thicker stroke. Clicking the same legend item again clears the filter. The visualization uses d3.geoNaturalEarth1 and d3.geoPath for map projection, d3.zoom for pan and zoom, and scaleOrdinal with schemeSpectral for color encoding. Data comes from the World Atlas TopoJSON dataset, with country names and economy values loaded from TSV metadata.

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 displays global economic classifications using a color scale, with a legend that supports interactive filtering. Clicking a legend category dims other categories, highlighting only the selected economy type on the map. The visualization uses d3.geoNaturalEarth1 projection and d3.geoPath for rendering country shapes from TopoJSON data, with d3.zoom for panning and zooming. The legend is built with custom SVG elements, while colors come from the d3.schemePuBuGn ordinal scale.
