This interactive map displays global economic classifications as a choropleth, with each country colored by its economy type. A legend of color swatches allows users to click a category and instantly filter the map, highlighting matching countries while dimming others, and clicking again clears the filter. Built with D3.js v5, the visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to render SVG paths from TopoJSON data, while `d3.scaleOrdinal` and `d3.schemeSpectral` define the color scale. Zooming via `d3.zoom` enables closer inspection of regions.

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.

Interactive choropleth map filtering

An interactive choropleth map displays global economic classifications using color-coded countries over a natural Earth projection. Clicking legend entries filters the map, dimming unselected economies and highlighting the chosen one while allowing zoom and pan through d3.zoom. The visualization uses d3.geoPath to render TopoJSON world-atlas data, d3.scaleOrdinal with schemeSpectral for color mapping, and SVG elements with transitions managed by D3’s data join. Hovering changes country fill to red, and tooltips show country names and values.

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.

Choropleth Map with Interactive Filtering

A choropleth map displays global economic classifications by country, with an interactive color legend that filters the map by hovering or clicking on a category. The d3-scaleOrdinal and schemeSpectral color scale map each economy type to a distinct color, while d3-geoPath and geoNaturalEarth1 render the world geometry from TopoJSON data. Clicking a legend item dims non-matching countries and highlights the selected group, with zoom support via d3.zoom. The map uses SVG and d3.v5 for all rendering and interaction.

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 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 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.

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.
