Forked from Map with Selectable Countries

A choropleth map displays countries color-coded by economy using D3's `geoNaturalEarth1` projection and `geoPath`. Users click countries to select them, which highlights the chosen nation while dimming others; clicking again deselects. A color legend using `scaleOrdinal` with `schemeSpectral` allows filtering by income group. Data loads from world-atlas TSV and TopoJSON files, with SVG rendering supporting zoom interactions via D3's `zoom` event.

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

A choropleth map colors countries by economic category, with clickable countries that highlight while all others fade, and a corresponding color legend allows filtering by category. Built with d3.v5, it uses `geoNaturalEarth1` projection, `geoPath` for rendering, and `zoom` for panning. Data comes from the World Atlas TopoJSON plus TSV metadata, and the ordinal color scale uses `schemeSpectral`. Clicking a country or legend item toggles the selected state.

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 interactive choropleth map visualizes world countries colored by economic classification, with a linked legend that filters the map based on selected categories. Clicking a country either selects or deselects it, dimming all other countries; clicking a legend category toggles the map to show only countries in that category. The map uses `d3.geoPath` with the `geoNaturalEarth1` projection, `d3.zoom` for pan and zoom, and `d3.scaleOrdinal` with the spectral scheme for coloring. Data comes from the world-atlas TSV and TopoJSON files, rendered as SVG paths.

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 interactive choropleth map displays world countries colored by their economic classification, with grayed-out, semi-transparent countries when one is selected. Clicking a country highlights it and shows its name and value in a tooltip; clicking again deselects it, and clicking a color legend swatch filters the map to that category. Built with D3 v5, it uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering SVG paths, and `topojson.feature` to convert TopoJSON from the world-atlas package, joined with TSV metadata containing ISO codes and economy data.

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 choropleth map displays global income groups, with countries colored by category and a legend allowing selection of specific values. Clicking a country highlights it, fades all others, and dims the sphere, while clicking the legend filters the map to matching countries. The visualization uses d3.geoNaturalEarth1, d3.geoPath, and d3.zoom for the map, with d3.scaleOrdinal and d3.schemeSpectral for colors, loading TopoJSON world data and TSV metadata from the world-atlas package.
