Forked from Map with Selectable Countries

This example presents a world map colored by each country’s economy group using an ordinal color scale. Clicking a country highlights it while dimming all others, and clicking again deselects it; the accompanying color legend also supports filtering by clicking its swatches. Built with D3 v5, it uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering SVG paths, `d3.zoom` for pan and zoom, and `d3.scaleOrdinal` with `schemeSpectral`. Country boundaries and metadata come from TopoJSON and TSV files loaded from the world-atlas package.

Map with Selectable Countries

This map displays the world’s countries colored by their economy classification, using an ordinal color scale and a natural Earth projection. Users can click any country to highlight it while dimming all others; clicking again deselects it. A separate, clickable color legend filters the map to show only countries within a selected economy group. Built with D3 v5, it uses `geoPath`, `geoNaturalEarth1`, and `scaleOrdinal` with `schemeSpectral`, and renders as SVG paths. Country data originates from the world-atlas TopoJSON and TSV files.

Map with selectable country

This example presents a world map with countries colored by economic category, where clicking a country highlights it and dims all others; clicking again deselects it. The visualization includes a color legend with clickable swatches that filter the map’s opacity. Built with D3 v5, it uses `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.zoom` for the interactive map, rendered as SVG. Country data comes from World Atlas TopoJSON, while economic classifications load from a TSV file. A sequential ordinal color scale based on `schemeSpectral` drives the fill colors.

Map with Selectable Countries

This interactive map displays countries color-coded by economy type using D3’s `geoNaturalEarth1` projection and `geoPath`. Clicking a country highlights it while dimming others, and clicking again deselects it; a `scaleOrdinal` legend with `schemeSpectral` colors supports filtering. The visualization uses topojson data from world-atlas and applies a zoom transform via d3.zoom. Selection state is managed by an internal `selectedCountryId` variable, updated through click handlers on country paths and legend ticks.

Map with Selectable Countries

This interactive map displays global economies using a color-coded choropleth, where clicking a country selects it and dims all others. The legend also supports click-to-filter, highlighting matching color values. Built with D3 v5, it uses `geoNaturalEarth1` and `geoPath` for the projection and rendering, with `zoom` for panning. Data comes from the World Atlas TopoJSON and TSV files, with color values mapped via `scaleOrdinal` and `schemeSpectral`.

Map with Selectable Countries

This example presents an interactive choropleth map of world countries colored by economic classification. Users can click countries to highlight them while dimming all others, and clicking again deselects. The visualization also includes a clickable color legend that filters which categories remain visible. Built with D3 v5, it uses `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.zoom` for map rendering and interaction, while the color scale uses `d3.scaleOrdinal` with `d3.schemeSpectral`. Country boundaries and names come from TopoJSON world-atlas data.

Map with Selectable Countries

This example shows a choropleth map of world countries colored by economic grouping, with interactive selection: clicking a country dims all others and highlights the chosen region, and clicking again clears the selection. A color legend filters the map to a single category. The visualization uses D3 v5 with `geoNaturalEarth1` projection and `geoPath` for rendering SVG paths, plus `zoom` for panning. Data comes from TopoJSON and TSV files via the world-atlas package, with colors assigned by `scaleOrdinal`.

Map with Selectable Countries

This map visualizes world countries colored by economic classification using a categorical color scale. Clicking a country highlights it while dimming all others, and clicking again deselects it. The map uses d3.geoNaturalEarth1 projection with d3.geoPath to render SVG paths from TopoJSON world-atlas data, while d3.zoom enables panning and zooming. A color legend with clickable swatches filters the map, and the visualization updates reactively through D3 data joins.

Map with Selectable Countries

This map visualizes global countries colored by economic group, with clicking a country highlighting it while dimming others and the map sphere. A color legend allows filtering countries by economic category, and hovering shows country names. The visualization uses d3.geoNaturalEarth1 projection, d3.geoPath for rendering SVG paths, d3.zoom for pan and zoom, and d3.scaleOrdinal with schemeSpectral for choropleth coloring. Data comes from World Atlas TopoJSON and TSV files, loaded via d3.json and d3.tsv.
