A choropleth map of the world colors each country according to its economic classification, with a color legend on the left. The map uses a natural Earth projection rendered with `d3.geoPath`, and country data comes from the `world-atlas` TopoJSON and TSV files. A sequential color scale based on `d3.scaleOrdinal` and `schemeSpectral` assigns hues, and hovering turns a country red via SVG CSS. The visualization is built with D3 v5 and the `topojson` library's `feature` function, with zoom capability via a custom `zoom` callback.

Choropleth Map

This choropleth map visualizes countries colored by their economic classification, using a spectral color scale to distinguish categories. The map renders geographic boundaries as SVG paths via `d3.geoPath` and a Natural Earth projection. Data is loaded from the World Atlas TopoJSON and TSV files, merged by country ID, then assigned to the `d3.scaleOrdinal` color scale. A custom legend shows color swatches with labels, and hovering highlights individual countries in red. Interaction includes zoom and pan through the `d3.zoom` event, which applies an SVG transform.

choropleth map

A world map rendered as a choropleth uses color to encode each country’s economy classification. Built with D3 v5 and topojson, the visualization loads geographic data from a 50m world-atlas JSON and TSV files, then projects it using `geoNaturalEarth1`. The `scaleOrdinal` color scale applies the `schemeSpectral` palette, while a custom legend displays the categories. Hovering turns a country red, and zooming is supported via the `zoom` event handler.

Choropleth Map

A choropleth map colors world countries by economic classification using a sequential ordinal scale and the Spectral color scheme. The visualization, built with D3 v5 and TopoJSON, renders countries as SVG paths via d3.geoPath with a Natural Earth projection, supporting zoom and pan. A custom color legend displays the categorical color scale, while country data is joined from the World Atlas TopoJSON and TSV datasets using Promises.

Choropleth Map

This choropleth map colors countries by their economic classification using a categorical ordinal color scale from `d3.scaleOrdinal` with the `schemeSpectral` palette. It renders world geography with `d3.geoPath` and a Natural Earth projection, loading TopoJSON country boundaries and TSV metadata from the world-atlas package. A custom color legend built with D3 selections appears alongside the map, while `d3.zoom` enables panning and zooming. The visualization uses SVG elements and includes hover effects that highlight individual countries.

Choropleth Map

A choropleth map colors world countries by economic grouping, using a spectral color scale and an accompanying legend. Built with D3 v5 and TopoJSON, it loads country boundaries and metadata from the world-atlas package. The map renders as SVG paths via `d3.geoPath` with a natural Earth projection, supports zooming through `d3.zoom`, and highlights countries on hover. The color legend is a custom component using `d3.scaleOrdinal` and `d3.schemeSpectral`.

Choropleth map

A choropleth map colors world countries according to their economic classification, with a color legend that filters and highlights selected categories. Users can click legend entries to dim non-matching countries and intensify the selected region. Built with D3.js, the visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to project TopoJSON data from the world-atlas package, while `d3.scaleOrdinal` with `d3.schemeSpectral` assigns colors. Interactive zoom via `d3.zoom` and SVG rendering provide the map interface.

Choropleth Map

This choropleth map visualizes global economic classifications by coloring each country according to its income group. Built with D3 v5 and TopoJSON, it uses an ordinal color scale with the spectral scheme and renders geographic shapes via `d3.geoPath` with a natural Earth projection. The map supports pan and zoom through D3’s zoom behavior, and hovering highlights countries in red. A custom legend, generated with appended SVG circles and text, displays the color categories, while data is loaded from the World Atlas TopoJSON and TSV files.

Choropleth Map

A choropleth map colors countries according to their economy type, with a custom ordinal color legend and hover interactions that highlight each nation. The visualization renders an SVG world map using a natural Earth projection via `d3.geoPath` and `d3.geoNaturalEarth1`, while supporting pan and zoom through `d3.zoom`. Data comes from the World Atlas TopoJSON and TSV datasets, processed with `topojson.feature` and loaded asynchronously. The color scale uses `d3.scaleOrdinal` with `d3.schemeSpectral`, and the legend is built with custom D3 enter/merge/exit selections.
